I just toyed around with some @daslabor fellows and LED panels. Since I am working at #imgly, a @9elements company, I just had to put our logo on it. An Arduino nano was too slow, but ESP8266 does the job. WiFi / #MQTT support is planned. :)
Tools: xtensa-lx106 toolchain built with esp-open-sdk, #ESP8266 Arduino, Adafruit GFX, PxMatrix, makeEspArduino build scripts, a NodeMCU v2 board, and a 32x16 P10 RGB panel.
