FreeTouchDeck

Features:

• ESP32 DevKitC (38pin)
• ili9488 TFT SPI 4-WIRE
• xpt2046 resistive touch controller

This board is created for the FreeTouchDeck project and the PCB-combiner board is open source. Due to the extensive documentation it was easy to port openHASP to the FreeTouchDeck.

3D Printed Cases~

You can find a 3D printable case on Thingiverse and Github.

Flashing~

The FreeTouchDeck can easily be flashed over USB like any ESP32 development board.

GPIO Settings~

These pins can be used freely as GPIOs:

PCB Blueprint~

The PCB Combiner is fully Open Source Hardware:

• Schematics
• PCB layout

HASP build_flags~

Specify the LCD Configuration to use and define the GPIOs in the environment build flags:

build_flags =
    ${env.build_flags}
    ${esp32.build_flags}
