This board has 3 Cayenn devices on it including a 3A laser driver for my 1W UV laser BDR-209, a 5A laser driver for my NUBM44 6W laser, and a 120V/12V relay combo to automate my air pressure coolant. They are all controlled by their own NodeMCU.

Each ESP8266 on the NodeMCU is running the ChiliPeppr Cayenn protocol, which is simply a way for ChiliPeppr to upload commands onto the 4MB flash memory of the device and then have the device synchronize to the sync signal coming into it from the coolant pin on the TinyG.
