Gp ctrl: common questions

What microcontroller does the Gp ctrl use?

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

How big is the Gp ctrl PCB?

The Gp ctrl measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gp ctrl?

124 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gp ctrl design files?

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

Can I use the Gp ctrl design in my own project?

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

Can I test firmware for the Gp ctrl 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.
