Circuitcheck: common questions
What microcontroller does the Circuitcheck use?
The Circuitcheck is built around the PIC16F688, from the PIC family.
How many components are on the Circuitcheck?
77 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the Circuitcheck design files?
From the circuitcheck-1/circuitcheck repository on GitHub, which has a netlist; the links under Design files point to each one.
Can I use the Circuitcheck design in my own project?
The repository has no license, so all rights stay with circuitcheck-1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Circuitcheck without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
