Product Introduction
General
The F8L10 EVB is a test and development board for LoRa modules. It features
various interfaces including an antenna interface, JTAG interface, module SMT
interface, module pin header interface, F8L10S N interface, terminal
interface, serial DB9 interface, USB interface, jumper interface, module
antenna connector, etc. The board is equipped with power indicator lights,
serial communication indicator lights, three channel I/O interface indicator
lights, three channel ADC pin buttons, and a reset button, as shown in Figure
Note: The configuration board is set to default upon factory release. The jumper cap (J36) on the right side is set to 3.3V by default. If testing the F8L10D-E module for optimal testing distance (maximum transmit power):
- When powered by USB, short the jumper cap (J36) on the left side for module supply voltage of 5V and disconnect J11.
Recommendation: This configuration board is designed for LoRa module development and testing purposes.
Interfaces
Antenna Interfaces
The antenna interface features a standard SMA female connector.
JTAG Interfaces
The JTAG interface is used for downloading chip programs, and it has two
interfaces. One is a 5-pin single-row 2.0 interface (J10), as shown in Figure
2.
Module SMT Interfaces
Module SMT interface consists of dual-row pins as shown in Figure 3.
Note: Interface definitions can be referred to the F8L10D Module User Manual.
Module Pin Interface
The module pin header interface is a 2×8 dual-row pin header, as shown in
Figure 4. Due to pin limitations, only a subset of the module’s interfaces is
exposed through this interface. The SMT interface includes all interfaces
extended from the module.
Note: Interface definitions can be referenced in the F8L10D Module User Manual.
F8L10S-N Module Pin Interface
Module Pin Header Interface is a single-row pin header with a center-to-center
spacing of 2.54mm, as shown in Figure 5.
Note: Interface definitions can be referred to the F8L10S-N User Manual.2.6 Terminal Interface
Terminal Interface
Terminal Interface is a combination of power, serial, I/O pins, and ADC. As
shown in Figure 6, VDD5 voltage range is 520mA; NU_ADC2 is voltage collection,
with a voltage range of 0~5V; NU_IO1, NU_IO2, and NU_IO3 correspond to SMT
interface IO1, IO2, and IO3 respectively.
Table 2-1: Terminal Interface Definitions
| Number | Interface Name | SMT Interface |
|---|---|---|
| J14-1 | VDD5 | N/A |
| J14-2 | GND | GND |
| J14-3 | GND | GND |
| J14-4 | NU_TXD | USART_TX |
| J14-5 | NU_RXD | USART_RX |
| J14-6 | NU_RTS | USART_RT |
| J14-7 | NU_CTS | USART_CT/IO1 |
| J14-8 | NU_ IO2 | IO3 |
| J14-9 | NU_ IO1 | IO2 |
| J14-10 | NU_ADC2 | ADC2 |
| J14-11 | NU_ADC1 | ADC1 |
| J14-12 | NU_ADC0 | ADC0 |
Serial DB9 Interface
Serial DB9 Interface serves as the connection between the device and external
peripherals. When connecting this interface to a computer, a crossover cable
is required. In other words, the serial cable connections should be as
follows: Pin 2 connects to Pin 3, Pin 3 connects to Pin 2, and Pin 5 connects
to Pin 5.
Table 2-2: Definition of DB9 Interface
| DB9 Pin | Pin Header Interface | Pin Name |
|---|---|---|
| 2 | USART_RX | RX |
| 3 | USART_TX | TX |
| 5 | GND | GND |
| 7 | USART_RT | RTS |
| 8 | USART_CT | CTS |
Module Antenna Connector
The module antenna connector is used to connect the LoRa antenna socket
(MM9329-2700/Murata), as shown in Figure 7: Antenna Socket.
The structural dimensions of MM9329-2700/Murata are shown in Figure 8:
Indicator Lights/Buttons
Serial Communication Indicator Light
The serial communication indicator will flash when the device’s serial port is
in communication. The indicator remains off when there is no communication.
The circuit diagram is shown in Figure 9.
Three-channel I/O Interface Indicator Lights
The indicator lights for the three I/O interfaces are controlled by
transistors Q1, Q2, and Q3, respectively, through the SMT interfaces IO1, IO2,
and IO3. Refer to Figure 10 for details.
Three-channel ADC Pin Buttons
The three ADC pin buttons are used for calibration. Press the corresponding
button and use the software to calibrate the ADC value to its maximum when
held down. Release the button and use the software to calibrate the ADC value
to 0; this is a two-point calibration for ADC. As shown in Figure 11, ADC0 and
ADC1 are used for current collection (05V).
Reset Button
Reset Button is used to reset the LoRa module. When this button is pressed,
the RESET pin is set to low, causing the LoRa module to stop running. When the
button is released, the RESET pin is set to 3.3V, allowing the LoRa module to
start and run its program. The circuit is shown in Figure 12. VCC represents a
3.3V voltage.
