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.

Pros Cons
480x320 Display 4 MB flash
Price No PSram
Build Instructions Resistive touch

This is a kit so you need to assemble the parts yourself. Some soldering skills are required. You can 3D print a custom enclosure.

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
