【RA】LoRaWAN multi-function node development board based on Renesas RA

RALoRaWAN_Board V1.0 
 
R7FA2E1A72DFL is an entry-level single-chip microcontroller of the RA series, based on a 48 MHz Arm® Cortex®-M23 core, with up to 64 kB of code flash and 16 kB of SRAM. * 48MHz Arm® Cortex®-M23;
 
R7FA2E1A72DFL parameters: * Wide operating voltage range of 1.6V - 5.5V; * Enhanced capacitive touch sensing unit (CTSU); * Independent SPI interface/I2C multi-master interface; * 12-bit ADC, LPACMP, temperature sensor; * 32-bit general-purpose PWM timer, 16-bit general-purpose PWM timer, low-power asynchronous general-purpose timer;
 
Engineering features:
1. Still uses the mainstream interface Type-c.
2. The serial port uses the CH340N chip and communication indicator light.
3. Onboard AHT21 temperature and humidity sensor.
4. One reset button, one BOOT mode selection, and two user-defined buttons.
5. Three custom LEDs on board.
6. Buzzer on board.
7. RA-08 LoRaWAN module on board.
8. OLED screen with IIC protocol reserved.
9. One adjustable resistor on board for ADC learning.
10. SWD test is introduced for external simulation.
11. Power indicator light, hehe.
The PCB adopts the Aruino appearance, but it is not compatible with other Arduino expansion boards! !
