DCC Accessory Controller PCB

Design and write firmware for a small board to enable accessories to be controlled from a model railway track using DCC. OK, nothing new, I could have bought something to do this off the shelf. However I need a fair few of these and I like a challenge so "build your own" was obviously the way to go. Foundational to the project was the ability to get the PCB design as simple as possible to minimise cost and complexity. I was delighted to get the board down to a single sided PCB of just 50x75mm based around an Arduino Nano. PCB Way checked the CAD files and that they were going to produce what I anticipated and in less than a couple of week a stack of 20 perfect PCBs arrived. The PCBs arrived well packed and protected and are all flawless, it just remains for me to start building them. Thank you PCB Way.
