# Board support
|

If you wish to add support for a specific board to the project, all you have to do (if it's ESP32 or nRF52), is write an additional entry for `Boards.h`.
|

If you wish to add support for a specific board to the project, all you have to do (if it's ESP32 or nRF52), is write an additional entry for `Boards.h` and `Utilities.h` and the `Makefile` .
|

|

This entry should include, at a minimum, the following:
|
||||
### Boards.h
|
||||
This entry in `Boards.h` should include, at a minimum, the following:
|
||||
* whether the device has bluetooth / BLE
|
||||
* whether the device has a PMU
|
||||
* whether the device has an EEPROM (false in all cases for nRF52, true for ESP32)

### Utilities.h
|
||||
you should add something like this to drive the led :
|
||||
|
||||
```
|
||||
#elif BOARD_MODEL == BOARD_GENERIC_ESP32_C3
|
||||
void led_rx_on() { digitalWrite(pin_led_rx, HIGH); }

void led_rx_off() { digitalWrite(pin_led_rx, LOW); }

|

void led_tx_off() { digitalWrite(pin_led_tx, LOW); }

```
|
||||
|

### Makefile
|
||||
|
||||
one entry to build the firmware
|
||||
```
|
||||
firmware-genericesp32c3:
|
||||
arduino-cli compile --fqbn esp32:esp32:esp32c3:CDCOnBoot=cdc -e --build-property "build.partitions=no_ota" --build-property "upload.maximum_size=2097152" --build-property "compiler.cpp.extra_flags=\"-DBOARD_MODEL=0x3B\""
|
||||
```
|
||||
pay attention the the DBOARD_MODEL= value as you must choose an unsigned one for your board.
|
||||
|
||||
one entry to upload the firmware to the board
|
||||
|
||||
```
|
||||
upload-genericesp32c3:
|
||||
arduino-cli upload -p /dev/ttyACM0 --fqbn esp32:esp32:esp32c3
|
||||
@sleep 1

rnodeconf /dev/ttyACM0 --firmware-hash $$(./partition_hashes ./build/esp32.esp32.esp32c3/RNode_Firmware_CE.ino.bin)
