You must use the console to upload the firmware on the MAC or Linux platform. First, ensure you have installed esptool for Python. You can find it on the manufacturer's website, ESPRESSIF, [here](https://docs.espressif.com/projects/esp-at/en/latest/esp32/Get_Started/Downloading_guide.html).

## FLASH LED issue ## FLASH LED issue
The board has a problem with the FLASH LED, as it lacks any current limitation for the LED. Consequently, frequent use of the FLASH LED can lead to corruption, due to excessive current flow. The board has a problem with the FLASH LED, as it lacks any current limitation for the LED. Consequently, frequent use of the FLASH LED can lead to malfunction, due to excessive current flow.
One simple solution is to connect an external LED via a relay, transistor, or MOSFET to the board, as shown in the next picture. Using a relay is not ideal, but it provides a simple solution.
