Shifter: common questions

What microcontroller does the Shifter use?

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

How big is the Shifter PCB?

The Shifter measures 49.5 × 49.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Shifter?

43 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Shifter design files?

From the janc18/CAE32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Shifter design in my own project?

Yes, under the terms of its GPL-3.0 license, which janc18 chose for the repository.

Can I test firmware for the Shifter 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.
