An FM receiver board built around the RDA5807 module. It includes a Seeed Xiao RP2040 to control the RDA5807 over I2C. The board also includes a TDA2822 audio amplifier, which allows you to connect and drive speakers directly from the board. The RDA5807's antenna input is connected to a 3.5mm jack, so you can plug in a 3.5mm antenna.

Questions
How big is the Radio Tutorial PCB?
It measures 80 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Radio Tutorial use?
20 parts, built around the TDA2822NBD and PJ-3200. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Radio Tutorial KiCad files?
From the Outdatedcandy92/Radio-Tutorial repository on GitHub, at the commit this page was made from: the board is src/pcb/Radio_Tutorial.kicad_pcb and its schematic src/pcb/Radio_Tutorial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radio Tutorial design in my own project?
Its repository states no licence, so its author keeps all rights: ask Outdatedcandy92 before reusing the design.
