About the Radio-Tutorial PCB

Radio-Tutorial is an open source RP2040/RP2350 PCB design by Outdatedcandy92, published on GitHub. It is a 2-layer board measuring 80 × 35 mm, with 16 components from 11 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. Other key parts include the RDA5807MRRD-102V2.0 and TDA2822NBD. By type, the board carries 5 capacitors, 3 ICs, 3 connectors, 2 resistors and 1 switch.

It belongs with the audio and rf & radio designs in this gallery.

From the project

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 connect

Radio-Tutorial: common questions

What microcontroller does the Radio-Tutorial use?

The Radio-Tutorial is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Radio-Tutorial PCB?

The Radio-Tutorial measures 80 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Radio-Tutorial?

16 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Radio-Tutorial design files?

From the Outdatedcandy92/Radio-Tutorial repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Radio-Tutorial design in my own project?

The repository has no license, so all rights stay with Outdatedcandy92. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Radio-Tutorial without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
