Rp2040 trackball mouse: common questions

What microcontroller does the Rp2040 trackball mouse use?

The Rp2040 trackball mouse is built around the PT5529B/L2/H3, from the RP2040/RP2350 family.

How big is the Rp2040 trackball mouse PCB?

The Rp2040 trackball mouse measures 92 × 57 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp2040 trackball mouse?

29 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rp2040 trackball mouse design files?

From the h7ga40/rp2040_trackball_mouse_pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rp2040 trackball mouse design in my own project?

Yes, under the terms of its CC0-1.0 license, which h7ga40 chose for the repository.

Can I test firmware for the Rp2040 trackball mouse 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.
