About the RP2040-mini-SDR PCB

RP2040-mini-SDR is an open source RP2040/RP2350 PCB design by Keyaan-07, published on GitHub under the MIT license. It is a 4-layer board measuring 74.3 × 20 mm, with 51 components from 25 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the PSA4-5043+, ADE-11X+, SI5351A-B-GTR, GALI-84+ and ADCS7476AIMFX/NOPB. By type, the board carries 26 capacitors, 8 ICs, 7 resistors, 4 inductors, 2 crystals and 2 connectors.

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

From the project

An attempt to make an SDR using the RP2040.

I am in no way an RF expert and would love it if someone pointed out my errors and mailed them to me or DM on hackclub Slack

I think I am gonna make another RF board that could legally transmit too! but that's just an idea for now.

I am not making a 3D model for this project as i feel this is not required for now.

So, i planned to make out an SDR using the goated RP2040 chip and a few mixers and oscillators.

RP2040-mini-SDR: common questions

What microcontroller does the RP2040-mini-SDR use?

The RP2040-mini-SDR is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040-mini-SDR PCB?

The RP2040-mini-SDR measures 74.3 × 20 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2040-mini-SDR?

51 components, from 25 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 RP2040-mini-SDR design files?

From the Keyaan-07/RP2040-mini-SDR 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 RP2040-mini-SDR design in my own project?
