This project a spin-off the ECCB display project. The objective is to build a proof of concept for a low-power bus-stop display to replace existing power-hungry LED displays.


A new controller is designed to interface the ECCB bi-pane signals with the RS232 based command structure that comes from the existing connectivity controller in the bus stop.
