Rusb pd second: common questions
What microcontroller does the Rusb pd second use?
The Rusb pd second is built around the CH32V003FxUx, from the RISC-V family.
How big is the Rusb pd second PCB?
The Rusb pd second measures 25.5 × 24.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Rusb pd second?
31 components, from 23 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rusb pd second design files?
From the ambraglow/rusb-pd repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Rusb pd second design in my own project?
Yes, under the terms of its GPL-3.0 license, which ambraglow chose for the repository.
Can I test firmware for the Rusb pd second 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.
