This board was originaly created for the FreeTouchDeck project and the hardware is also open source. Due to the extensive documentation it was easy to port openHASP to the ESP32-Touchdown.
|480x320 display||4 MB flash|
|Capactitive touch||No PSram|
The speaker and SD card are not supported by openHASP 0.6.2.
Any 3.7V (nominal voltage) LiPo will work, 2000mAh battery should suffice. Be sure to have the correct polarity. If the connecter at the end of the battery does not match, gently remove the pins from the connector and put them back in the correct orientation.
To enable backlight control, make sure the solder jumper pad is in position 2-1:

The ESP32 TouchDown can easily be flashed over USB like any ESP32 development board.
These pins can be used freely as GPIOs:
The ESP32 TouchDown is fully Open Source Hardware:
