The RFµ (or RFu, for the purposes of people being able to Google this without trying to type µ) 328 is a really neat little board from wireless vendor Ciseco. I picked one up for a project I’m doing where I need a low power microcontroller and some way to talk to a base station with power. This is basically what this board is – an integrated ~896MHz radio module and microcontroller. The radio module works as a serial link so it’s really easy to work with, and the microcontroller is the Arduino compatible ATmega 328 chip, complete with the Arduino Uno bootloader.
There were some stumbling blocks I figured I’d document here, though, to get to the point where you can throw code at this thing and have it work, entirely over the air. Continue reading Tinkering with the RFµ-328
