Whether you’re new to electronics and programming, or you were bit-banging bare metal long before hair metal, CircuitPython is a great tool for getting a project up and working without all the fuss. The boards show up as mass storage devices, and programming consists of editing the Python file and saving it back to the board.

The only hard part about CircuitPython is trying to cram those official boards into small projects. [Kevin Neubauer] got tired of making his own board every time and came up with a slim system-on-module that has all the core functionality of CircuitPython. CircuitBrains Deluxe has regular holes for using headers, but also has castellated pads so he can solder these modules directly to a larger project PCB. [Kevin] says these are still in the testing and cost-optimization phase, but we would totally buy a few of them.

[Kevin] probably has a programming method for this module in mind already. But if you find yourself mystified by castellated pads, take a look at this pogo pin programmer built for ESP8266s. If your problem is pitch-related, maybe you can save the day with a breakout board.

Thanks to [Drew Fustini] for the tip!
