RIGADO BMD-360-EVAL RF or Wireless Development Boards and Kits

Introduction

The BMD-3xx-EVAL kits from Rigado allow for stand-alone use of the BMD-300, BMD-301, and BMD-350 modules featuring the Nordic nRF52832 RF System on Chip (SoC), the BMD-330 module featuring the Nordic nRF52810 RF SoC and BMD-360 module featuring the Nordic nRF52811 RF SoC. Other Rigado modules have evaluation kits covered by other documents.
These Evaluation Kits provide a great starting point for almost any Bluetooth 5 Low Energy project. All features of the BMD-3xx are easily accessed from the evaluation board. A simple USB connection provides power, programming, and a virtual COM port. Four user buttons are available, as well as four LEDs and a reset button. All 32 GPIO are available on headers that are compatible with the Arduino form factor. This allows easy use of any existing Arduino shields. Current sense resistors allow for measuring current into the BMD-3xx module and into the shield.
This guide provides setup instructions for starting development and describes the hardware functionality of the BMD-3xx-EVAL boards.

Application Firmware Development

This section walks through how to set up and program the BMD-300 Series Evaluation Kit with an example application.

Set up the tool chain

1. Install Segger Embedded Studio and request a license.

2. Download the latest nRF5 SDK. Unzip it to a convenient working directory. Be sure not to alter the directory trees. The examples are configured for relative path positions.

3. Install nRF Connect on desktop PC and optionally one of the mobile versions. nRF Connect can be used directly with the Device Under Test (DUT) Eval board for programming and other features.
   If using nRF Connect on a desktop, a second Eval board or a nRF52 USB Dongle will be needed to make BLE connections with your DUT.

4. Install the Segger J-Link Commander. If presented with a screen to select different IDEs, ensure at least the EGGER Embedded Studio ARM line is selected:

5. You may need to add the install location to the system PATH. The default location for the J-Link Commander is: C:\Program Files (x86)\SEGGER\JLink_Vnnn … where “nnn” is the version number.

6. Install nRF Toolbox for your mobile device. This will be used with the example below.

Connect BMD-3xx-EVAL to computer

The evaluation board is provided with an on-board Segger J-Link programmer/debugger.

1. Connect the board to a computer using the USB cable provided.
2. The status LED, D5, will flash and then turn solid once the USB device is enumerated.
3. After a few seconds the computer will recognize the Evaluation Board as a J-Link device and install the USB-Virtual COM Port device driver.
4. Run the J-Link Commander:
5. JLink on Windows
6. JLinkExe on macOS and Linux
7. Type “connect” at the J-Link> prompt
8. Enter the device type at the Device> prompt
9. Type nRF52832_XXAA for the BMD-300, BMD-301, or BMD-350
10. Type nRF52810_XXAA for the BMD-330
11. Enter S to select the SWD interface and accept the default for the speed.
12. J-Link will respond with several items. Here is a sample output:
13. This confirms that the Eval board is properly recognized.
14. While still in the J-Link Commander session, save the Rigado-programmed public MAC address by typing in: savebin mac_addr.bin 0x10001080 8
15. Exit the J-Link session by typing exit
16. At this point, a file titled mac_addr.bin will be saved in the current directory. The contents will contain the MAC address in little-endian format: 33 22 11 93 54 94 FF FF to correspond to the address 94:54:93:11:22:33. The last two FF values are only fillers to complete the 8-byte read. Rigado MAC addresses begin with the IEEE-assigned company ID (94:54:93). The remaining bytes are printed on the 2D and human-readable label on the module. See the MAC Address Provisioning KB article for additional information.
17. This file may be used to restore the MAC address after performing an erase or recover with the J-Link command
18. loadbin mac_address.bin 0x10001080

Prepare the module for programming

The BMD-3xx module is shipped from the factory with factory firmware to support legacy designs. This firmware must be removed prior to programming new code. Run the following at a command prompt: nrfjprog -f nrf52 –recover

Open an example project

Note : When selecting examples from the SDK, note the following cross reference:

select PCA10040)
BMD-360-EVAL| nRF52811| PCA10056e / nRF52840 DK (If PCA10056e is not available, select PCA10056)

For this guide, the nRF SDK v15.2.0 Heart Rate Service example for the BMD-300-EVAL will be used. The latest SDK version should be used whenever possible. The “nRF5_SDK_xx.x.x_yyyyyyy” directory may change. The folders under usually remain the same from version to version.

1. Navigate to the location of the heart rate example from the SDK, typically \nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_hrs

2. Select the DK Board, SoftDevice and IDE directories. Here is the full path: \nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_hrs\ pca10040\s132\ses

3. Open the project file (ble_app_hrs_pca10040_s132.emProject) to start the Segger Embedded Studio IDE

4. Build the project ()

5. Once the build is successful, you can download the application code onto the module Board (Target | Download ble_app_hrs_pca10040_s132)
   The first time the board is loaded, both the SoftDevice and the application will be downloaded to the BMD-300. Once the SoftDevice is loaded, subsequent downloads will only transfer the application. If you need to change SoftDevice versions, repeat section 5.3 Prepare the module for programming above.

6. On a mobile device, open the nRF Toolbox application. Select the Heart Rate Monitor.

Hardware Description

Design files for each of the BMD-3xx-EVAL boards may be found on the Rigado website.

Power

The BMD-300 Evaluation Board has three possible power sources: USB, a CR2032 coin cell battery, and a 0.1” through-hole connector. These power sources use protection diodes to prevent reverse voltage to any supply. This allows them to be used simultaneously. Solder jumpers are provided to allow bypassing any of the protection diodes eliminating the voltage drop across them. Care should be taken to not damage the supplies when the protection is by-passed

Powering the Board:

Typically, power will be provided by USB though VBUS, which will supply +5V to the 3.3V LDO regulator and to the shield connector. The 3.3V LDO regulator will then power the VIO, VSHLD, and VBMD.
When powering the board from the CR2032 coin cell (3VDC) or the external power header, USB can be left disconnected. In this configuration, the interface IC is held in reset to conserve power. Only if the power protection diodes are left intact, USB can be connected at the same time the coin cell or external power is still applied allowing for easy programming of the module.

Reset

The BMD-300 Series module has a configurable hardware reset. However, P0.21 is assumed to be used as the reset pin for all Rigado and Nordic example projects, and thus the evaluation board hardware is configured to use P0.21 as a reset. The Reset button can be configured to connect to an input on the interface IC or to directly connect to P0.21.
The Reset button is connected to the IC used for the J-Link interface by default. Pressing reset while the interface IC is powered will caused a momentary reset signal on the nRESET output of the interface IC, which is connected via solder jumper to P0.21 of the BMD-300 Series module. If the Reset button is held down during power on, it will cause the interface IC to enter its bootloader mode,
allowing either Segger J-Link or mbed programmer firmware to be programmed.
When the Reset button is directly connected to P0.21, it can be used as a 5th user button or as a reset button directly connected to the BMD module. Solder jumper J21 is used to connect P0.21 of the BMD module to the nRESET net. nRESET is connected to the interface IC and to the reset connections on the Arduino headers.

Buttons

The Evaluation Board has four user buttons: User 1, User 2, User 3, and User 4. All buttons are active low; they will connect to ground when pressed. The button GPIO pins must be configured with internal pull-up resistors for proper operation when using the user buttons. The buttons and ESD protection can be completely removed from the circuit by breaking the associated jumper.

LEDs

Four User LEDs are provided on the Evaluation Board; two red and two green. LEDs are powered by VIO and are active low. The GPIO should be enabled for high drive when sinking current for the LEDs. The LEDs can be completely removed from the circuit by breaking the associated jumper

Virtual COM Port

The evaluation board allows for easy serial communication with the BMD-300 Series Modules and a connected computer. The Interface IC provide a virtual COM USB device that connects to 4 GPIO pins on the module, allowing for UART communication with or without hardware flow control. The UART lines can be completely removed from the circuit by breaking the associated jumpers

32kHz Crystal Oscillator

The evaluation board has a 32.768kHz Crystal Oscillator connected to the BMD- 3xx module by default. This allows the module to use any of the three available low frequency (LF) clock sources: an internal calibrated RC oscillator, an internal synthesized clock (derived from the 32MHz clock), or an external crystal oscillator. The external crystal oscillator is the most accurate and lowest power LF clock option. For applications without strict time keeping requirements, the internal calibrated RC oscillator is often suitable. The crystal is connected to the module through a solder select jumper, allowing either the crystal or the IO header to be connected to the module’s GPIO pins.

NFC Connector

Connection to an external NFC antenna is provided through a Molex flat-flex connector, Part number 051281-0594. Capacitors ‘C2’ and ‘C3’ provide tuning of the NFC antenna for resonance at 15.56MHz.
Note: NFC is not supported on the BMD-330. These components are not populated on the BMD_330-EVAL.

Current Sensing Headers

The evaluation board provides two current sensing headers. ‘JBMD’ allows for power consumption measurement of the BMD-300 Series Module and ‘JSHD’ allows for power consumption measurement of shields connected to the Arduino-style headers (‘VSHLD’ power only).
Each 3-pin 0.1” pitch header has two pins connected across a 1Ω current-sense resistor powering the module or the shield, and the third pin to ground. To measure current consumption, use a multimeter or other precision voltage measurement device to measure voltage drop across pins one and two.
Current can also be measured directly by removing ‘RBMD’ / ‘RSHD’ and using a current meter in series with the two voltage pins. The default hardware configuration does not require any modification of the current sense headers for the BMD-3xx-EVAL to perform properly.

Note: Only current flowing through ‘VBMD’ into the module is measured; current sunk through GPIO pins is not measured.

External Segger J-Link™ Debug Interface

External target hardware can be connected to J3 for firmware programming and debug. The Segger debug interface is implemented as shown in Figure 12. J3 is implemented with a 2×5 10-pin header on 0.05” centers.

In order to enable the external J-Link connection, ensure the following are implemented on the target hardware:

• EXT_VTG is used by the debug interface as an input to sense power applied to the external circuit. Only voltages of ~3.0V to ~3.3V are supported. Other operating voltages require the use of an external J-Link Debug Probe. Connect EXT_VTG to the BMD-300 Series power supply (VCC) on the target hardware.
• EXT_GND_DETECT is used by the debug interface to detect the presence of external target hardware. Connect EXT_GND_DETECT to GND on the target hardware.
• Connect EXT_SWDIO and EXT_SWCLK to SWDIO and SWDCLK on the target BMD-3xx, respectively.
• (Optional) Connect EXT_SWO and/or EXT_RESETn to P0.18 and P0.21 on the target BMD-3xx,\ respectively.
• Connect external power to the target hardware, then connect the BMD-300 Series Evaluation Board to USB.
• At this point, the debug interface will interact with the target hardware instead of the on-board BMD-3xx.

GPIO Jumpers

There are many solder bridge jumpers on the board available to allow for configurability of the GPIO. Most solder jumpers are used to remove on-board components from the module’s GPIO nets, should they interfere with external circuitry added on the I/O headers. All GPIOs are directly connected to the I/O Headers by default, except P0.00 & P0.01 (32kHz crystal) and P0.09 & P0.10 (NFC antenna). These are disconnected from the I/O headers as they would interfere with the default functions

The GPIO jumpers are shown on the bottom side of the BMD-300 Series Evaluation Board:
