ErgoSHIFT-rev2: common questions

What microcontroller does the ErgoSHIFT-rev2 use?

The ErgoSHIFT-rev2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the ErgoSHIFT-rev2 PCB?

The ErgoSHIFT-rev2 measures 233.2 × 147.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ErgoSHIFT-rev2?

51 components, from 17 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 ErgoSHIFT-rev2 design files?

From the mizma/ergoSHIFT 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 ErgoSHIFT-rev2 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which mizma chose for the repository.

Can I test firmware for the ErgoSHIFT-rev2 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.
