Description

Controller Board for the IV-25 Display Module. It is basically a USB-C NodeMCU Board with onboard 5V and 3,3V regulator, a MOSFET for switching the Cathode on and off and extension ports for the Anode / Cathode Step-Up/Downs and the actual display modules. I also added an expansion header that allows for i2c devices to be connected to the controller. I am planning on using a laser distance sensor as a "movement detector" to activate the display only when someone is standing in front of it.

For more infos check the github repo and the hackaday.io page.
