About the Spoon22k PCB

Spoon22k is an open source RP2040/RP2350 PCB design by strickyak, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 96 mm, with 33 components from 12 distinct parts.

Its main chip is the PicoW, from the RP2040/RP2350 family. Other key parts include the C6818 and C7859. By type, the board carries 10 connectors, 10 capacitors, 8 ICs, 4 test points and 1 jumper.

Spoon22k: common questions

What microcontroller does the Spoon22k use?

The Spoon22k is built around the PicoW, from the RP2040/RP2350 family.

How big is the Spoon22k PCB?

The Spoon22k measures 100 × 96 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Spoon22k?

33 components, from 12 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 Spoon22k design files?

From the strickyak/copico-bonobo 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 Spoon22k design in my own project?

Yes, under the terms of its MIT license, which strickyak chose for the repository.

Can I test firmware for the Spoon22k 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.
