About the PicoGamePad PCB

PicoGamePad is an open source RP2040/RP2350 PCB design by Michael-Lloyd, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 68.9 × 37.6 mm, with 49 components from 33 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the ASM1117-3.3 and WQ25JVS. By type, the board carries 18 capacitors, 8 switches, 7 resistors, 6 test points, 3 ICs and 2 connectors.

It belongs with the dev boards & breakouts and retro computing designs in this gallery.

From the project

RP2040 Gamepad and Microcontroller Breakout Board. Type A is used for teaching students to reflow SMD @ UNSW Makerspaces.

This section is still a work in progress. I need to finish some other things first.

PicoGamePad: common questions

What microcontroller does the PicoGamePad use?

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

How big is the PicoGamePad PCB?

The PicoGamePad measures 68.9 × 37.6 mm, has 4 copper layers and is 1.02 mm thick.

How many components are on the PicoGamePad?

49 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the PicoGamePad design files?

From the Michael-Lloyd/PicoGamePad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PicoGamePad design in my own project?

Yes, under the terms of its GPL-3.0 license, which Michael-Lloyd chose for the repository.

Can I test firmware for the PicoGamePad 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.
