Program your board using the esptool.py program, found here.

To place the board in bootloader mode - so `esptool`` can be used - press and hold the reset button for two seconds. A green LED will flash behind the reset button when the bootloader mode has been activated.

If you are putting MicroPython on your board for the first time then you should first erase the entire flash using:

esptool.py --chip esp32s3 --port /dev/ttyACM0 erase_flash

From then on program the firmware starting at address 0:

esptool.py --chip esp32s3 --port /dev/ttyACM0 write_flash -z 0 board-20240105-v1.22.1.bin

After the firmware has been deployed, press the reset button to reset the device and start the new firmware.
