Introduction

Welcome to INP301x Talaria TWO evaluation board user guide. This board is designed as an evaluation platform for the INP101x modules. This user guide provides an overview of the evaluation board explaining its key features and functions.

INP301x Package Contents
The package contains:

1. INP3010 or INP3011 board
2. Micro USB cable
3. Antenna (INP3011 board only)
4. Battery box

Description of the board

Block Diagram

The block diagram of the INP301x Evaluation board is shown in Figure 2. The main component on the board is the INP101x module. Key features of the evaluation board are:

1. Standalone mode vs. Shield mode: Using the mode switch U3, either standalone mode or shield mode can be selected.
   • a. In standalone mode, the INP101x can be accessed via micro USB cable for programming and debugging. This mode is recommended for standalone application development.
   • b. In shield mode, the INP101x module can be interfaced with any host CPU and can provide serial to Wi-Fi capabilities.
2. A peripheral IO header (J1) is available using which all the IO’s of the INP101x module can be accessed.
3. Power supply section: Based on the mode, the power for module is derived from either USB or shield header. A battery header is available which can be used as power source as well.
4. On board sensors are available to develop sensor to cloud applications.

Jumpers on the board

Power Supply and Mode Switch

The INP301x board is designed to supply power to the INP101x module in following ways:

1. In standalone mode, power is drawn from USB connector.
2. In shield mode, power is drawn from shield connector.
3. A battery header is also available to provide power to the module.

The power supply section is shown in the Figure 4. The INP101x module requires 3.3V supply. The DPDT switch (U3) selects between USB and Arduino header supply using the common net Vm_3.3V. The jumper J4 is used to select between battery supply and Vm_3.3V. The same jumper can be used for measuring current consumption of the module.

IO Header (J1)
The J1 header brings out all the IOs from INP101x module. These IOs can be used for debug, and/or any external interfacing needs. The pinout of this header is shown in Figure 5. To work with on board sensor, pins 1 & 2 needs to be shorted.

Shield Headers (JP1 to JP4)
Arduino UNO compatible headers are available in the INP301x board to interface with any compatible host micro-controller. The GPIOs assigned to shield headers are carefully chosen to achieve following capability:

1. INP101x’s SPI slave pins available on JP1
2. INP101x’s I2C master pins available on JP1
3. Remaining GPIOs are available on JP2 and JP4

Note that INP301x supports 2.5V IO as the default configuration. The shield header connections are shown in Figure 6.

On Board Sensors

The INP301x board has following sensors available on board for quick prototyping/testing:

1. Temperature/Humidity (Sensirion SHTC3)
2. Pressure (Bosch BMP388)
3. Light (TI OPT3002)

To use the sensors, J7, J8, pins 1 & 2 of J1 should be connected. This enables power connection to the sensors on board, I2C connection on GPIOs 3 & 4.

Functional Description

Following are the functional modes that can be achieved in the INP301x board:

1. Stand-alone mode
2. Shield mode

More details about each mode is available in subsequent sections. Switching between the modes is handled by DPDT switch U3 for power, and multi-port SPDT switch U1 for the GPIOs.

Stand-alone mode
The stand-alone mode is intended for following use cases:

1. Host-less application development on INP101x modules
2. Programming access to INP101x modules

In stand-alone mode, the U3 switch is pushed towards pin 3, which disconnects power and IO from shield headers and connects them to FTDI. The FTDI port layout is shown in

The A & B bus of FTDI device supports MPSEE protocol, hence JTAG is assigned to A-bus. The BDBUS7 is connected EN_CHIP of the INP101x module. The C & D bus of FTDI device used as UARTs, with C-bus connected to peripheral UART of INP101x module and D-bus connected is CONSOLE port (GPIO17) of INP101x module.
The JTAG on A-bus is used for debugging applications on the INP101x module. The UART on C-bus is used for programming the INP101x module. The CONSOLE port is a unidirectional UART from INP101x module that operates at high baud rate of 2457600, used for debug prints.

Driver Installation for Windows OS
On Windows OS, libusbK driver needs to be installed to communicate and control the Talaria TWO module via the FTDI device on the evaluation board. The tools/applications provided by InnoPhase will use this driver. Install/uninstall instructions for this driver is given subsequent sections.

Installation instructions for libusbK driver
Download the free software Zadig, available here: – https://zadig.akeo.ie/. Connect your Windows PC or Laptop to the evaluation board using the provided USB cable. Now, open Zadig and click on Options. Select List All Devices and deselect Ignore Hubs or Composite Parents as shown in Figure 9.

To establish communication with Talaria TWO module via the FTDI device on the InnoPhase Evaluation Board, the Talaria TWO USB driver must be libusbK. In case the current driver is not libusbK, use the drop-down menu to select libusbK and click on Reinstall Driver which will update the drivers to libusbK.

Uninstall instructions for libusbK driver
To uninstall libusbK and retrieve COM ports, follow the following steps:

1. Expand the libusbK USB Devices and right click on the InnoPhase T2 Evaluation Board. Click on Update Devices as shown in Figure 11.
   

2. On the new window, click on Let me pick from a list of available drivers on my
   computer option and click on Next.
   

3. Select USB Composite Device Driver and install the same for reinstalling COM posts.

Shield Mode
This mode will make the EVB-A board to act as a Wi-Fi shield. To enable this mode, flip the switch
U3 towards V33_ARD. This also pulls up the INA pin of the multi-port SPDT device MAX4761ETX,
which then routes the GPIOs from the INP101x module to the shield headers JP1, JP2, JP3 and JP4. In the shield mode a suitable firmware (such as Serial to Wi-Fi application available in the SDK)
should be pre-flashed in the INP101x.

EVB-A as Wi-Fi Shield with STM32 Nucleo Board
A comprehensive set of host application packages are available to download via ST or InnoPhase websites to demonstrate the use of EVB-A as a Wi-Fi/BLE shield board.

Power Measurement

The power consumption of the INP101x module is measured by either connecting a DMM on the jumper J4 or supplying power directly on J4 using specialty power supplies like Otti Arc from Qiotech. Error ! Reference source not found. shows the connection setup to measure current consumption using Otti Arc.

Using Battery as Power Source

Antenna

Talaria TWO INP1011 module has a U.fl antenna module. The antenna used is an Inventek 24002500Mhz with part number W24-SSMA-M.
It has the following specifications:

1. a) Gain(dBi): 2.15 (dBi refers to the signal power when compared to the output signal power of an isotropic antenna. Antenna gain is the ratio of the signal strength in the direction of strongest radiation to that of an ideal isotropic antenna.)
2. b) Return Loss (dBi): 17

The customer can either use the same part or a part with the same specification or a part with gain < 2.15 dBi and return loss < 17 dBi.

If the customer is compliant with the above specification, the FCC certification could be leveraged.

Power Supply

Talaria TWO INP1011 module is designed to use external power supply. It utilizes internal power management circuit including two high efficiency buck converters. External power can be delivered from battery or a power supply connected to pins 2, 3 and AGND. Voltage from power source should be between 2.7V to 4.0V.
