For SMD March we’ll be building an Internet of things board. This is the heart of an arduino uno coupled with an ethernet interface to let you control leds, relays etc, plus read switch positions, temperature etc. all over Ethernet.
Like a uno, it has a usb interface for programming with the Arduino GUI and measures just 5cm x 5cm. It’s the first board in our SMD series with components on both sides (does not present much of a challenge), it’s also the first board with errors on the pcb unfortunately – two mods to make.
If you don’t feel up to the soldering consider finding a friend to build one for you.
I’ve uploaded all the files and photos to github
