Switch Charging: common questions

What microcontroller does the Switch Charging use?

The Switch Charging is built around the RP2040-ZERO, from the RP2040/RP2350 family.

How big is the Switch Charging PCB?

The Switch Charging measures 209.2 × 129.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Switch Charging?

122 components, from 35 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 Switch Charging design files?

From the PMantix/Switch_Charging 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 Switch Charging design in my own project?

The repository has no license, so all rights stay with PMantix. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Switch Charging 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.
