Rev1: common questions

What microcontroller does the Rev1 use?

The Rev1 is built around the NCP114ASN330T1G, from the RP2040/RP2350 family.

How big is the Rev1 PCB?

The Rev1 measures 24 × 19.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rev1?

34 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rev1 design files?

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

Can I use the Rev1 design in my own project?

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

Can I test firmware for the Rev1 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.
