Crw-031: common questions
What microcontroller does the Crw-031 use?
The Crw-031 is built around the PIC32MX250F128D-IPT, from the PIC family.
How big is the Crw-031 PCB?
The Crw-031 measures 18.3 × 47 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Crw-031?
37 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Crw-031 design files?
From the caitlynrw/crw-pcbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Crw-031 design in my own project?
The repository has no license, so all rights stay with caitlynrw. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Crw-031 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.
