USBCpwr: common questions
What microcontroller does the USBCpwr use?
The USBCpwr is built around the CH585M, from the RISC-V family.
How big is the USBCpwr PCB?
The USBCpwr measures 43 × 45 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the USBCpwr?
10 components, from 10 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 USBCpwr design files?
From the wrickert/UntitledElectronics 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 USBCpwr design in my own project?
The repository has no license, so all rights stay with wrickert. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the USBCpwr 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.
