Custom FM Receiver with STM32 and RDA5807: Full Project Breakdown
I built an FM radio receiver. As usual, the goal was to “build something useful and learn something new along the way.” What made this project especially exciting was that it involved working with an STM32 microcontroller—something I hadn’t done before, even though I’ve had several dev boards and programmers lying around for years. I also really wanted to use the headphone wire as the antenna, just like in commercial devices.
