Bitluni Releases ESP32 VGA Board as a DIY Kit to Display Graphics on a VGA Screen

Back in February, Bitluni’s Lab detailed how to pump VGA video from an ESP32 microcontroller using a bunch of resistors, some external DACs, and a little programming. He was able to garner three color signals, and vertical and horizontal sync pulses into 24 bits to produce a 320 x 240 signal, and eventually pushed it to 460 x 480. Bitluni uploaded the schematic and code for those who wanted to undertake his ESP32 hack on his website, but now he’s offering it for sale in kit form with a price tag of $15.

The ESP VGA Board does away with the original breadboard design in favor of a custom PCB designed to act as a shield for use with an ESP32/32S Mini Kit (or similar platform). The board allows you to connect a standard VGA display to the microcontroller for what Bitluni states, “To display super fast graphics using my ESP32Lib Arduino library. Text, drawing functions, sprites, a 3D-engine and game controller support… What else do you need?”

The ESP32 VGA Board comes as a kit with everything needed to create the shield, such as resistors, VGA connector, and pins. The PCB features significant through-hole components that should make it easy to solder, even for beginners, making it an excellent board for VGA projects.

Of course, for those who would rather skip the soldering process, Bitluni’s Lab will put it together for you for an added fee ($15). Bitluni has also uploaded his ESP32Lib Arduino library that features example code for use with the board, which includes graphics, sound, and game controllers.
