The idea of a reconfigurable macro keyboard is a concept that has been iterated on by many all the way from custom DIY keypads to the polarizing TouchBar on MacBooks. The continual rise of cheap powerful microcontrollers with Wi-Fi and 3D printers makes rolling your own macro keyboard easier every year. [Dustin Watts] has joined the proverbial club and built a beautiful macro pad called FreeTouchDeck.

We’ve seen macro keyboards that use rotary encoders to cycle through different mappings for the keys. FreeTouchDeck has taken the display approach and incorporates a touch screen to offer different buttons. [Dustin] was inspired by a similar project called FreeDeck, which offers six buttons each with a small screen. FreeTouchDeck is powered by an ESP32 and drives an ILI9488 touch screen with an XPT2046 touch controller. This means that FreeTouchDeck can offer six buttons with submenus and all sorts of bells and whistles. A connection to the computer is done by emulating a Bluetooth keyboard. By adding a configuration mode that starts a web server, FreeTouchDeck allows easy customization on the fly.

[Dustin] whipped up a quick PCB that makes it easy to solder the ESP32 and the TFT together, but a breadboard works just fine. Gerbers for that are available on GitHub. To wrap it all up, a nice 3D printed shell encloses the whole system in a clean, tidy way. The code, documentation, and case designs are all on his GitHub.

Thanks [Dustin] for sending this one our way!
