Wire connect checker: common questions

What microcontroller does the Wire connect checker use?

The Wire connect checker is built around the CH32V003F4P6, from the RISC-V family.

How big is the Wire connect checker PCB?

The Wire connect checker measures 53.5 × 69.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Wire connect checker?

72 components, from 19 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 Wire connect checker design files?

From the 74th/74th-oshw-projects 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 Wire connect checker design in my own project?

Yes, under the terms of its MIT license, which 74th chose for the repository.

Can I test firmware for the Wire connect checker without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
