Barsotion-PL1: common questions
What microcontroller does the Barsotion-PL1 use?
The Barsotion-PL1 is built around the CH32V305GBU6, from the RISC-V family.
How big is the Barsotion-PL1 PCB?
The Barsotion-PL1 measures 33 × 20 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Barsotion-PL1?
47 components, from 25 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 Barsotion-PL1 design files?
From the Barsy-Barsevich/Barsotion-PL1 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 Barsotion-PL1 design in my own project?
Yes, under the terms of its MIT license, which Barsy-Barsevich chose for the repository.
Can I test firmware for the Barsotion-PL1 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.
