I have ControlBoard V3 (deprecated); so I had to grab the last firmware and info from an older commit on GitHub. ```bash brew install esptool # hold the BOOT button and while holding, run this command. once it starts running, you can release the boot button. esptool --chip esp32s3 erase_flash # get info on the board esptool --port /dev/cu.usbmodem83201 chip_id # flash the firmware esptool --chip esp32s3 --port /dev/cu.usbmodem83201 --baud 460800 write_flash -z 0x1000 ControlBoard_V3_latest.bin ``` ESP Boards - ESPTool Basics: [Flash ESP32 Firmware Like a Pro using esptool.py - Guide](https://www.espboards.dev/blog/standalone-esptool-basics/)
