Breadboard breakout board for 48pin QFP STM32F100

Quick and simple project to make an adapter PCB to use a QFP packaged MCU on a traditional through-hole breadboard.

I ended up making a double-sided PCB to support 2 different QFP sizes. One side set up for 48 pins, the other for 32pins. Usage is to populate one side or the other, not both….

Simple pin-out to two standard 24-pin headers. No on board components such as decoupling capacitors.

Here is the board in action on a breadboard and loaded up with a 48-pin STM32F100C8:


Eagle files for the board are on GitHub here.
