Picotouch pad proto: common questions

What microcontroller does the Picotouch pad proto use?

The Picotouch pad proto is built around the Pico, from the RP2040/RP2350 family.

How big is the Picotouch pad proto PCB?

The Picotouch pad proto measures 190 × 34 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Picotouch pad proto?

79 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Picotouch pad proto design files?

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

Can I use the Picotouch pad proto design in my own project?

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

Can I test firmware for the Picotouch pad proto 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.
