Servo & DC Motor Board: common questions
What microcontroller does the Servo & DC Motor Board use?
The Servo & DC Motor Board is built around the CH32V003JxMx, from the RISC-V family.
How big is the Servo & DC Motor Board?
The Servo & DC Motor Board measures 100.4 × 50.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Servo & DC Motor Board?
47 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Servo & DC Motor Board design files?
From the callmestiles/omniplexus repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Servo & DC Motor Board design in my own project?
The repository has no license, so all rights stay with callmestiles. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Servo & DC Motor Board 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.
