ControlBoard: common questions
What microcontroller does the ControlBoard use?
The ControlBoard is built around the ARDUINO_UNO_R3, from the RP2040/RP2350 family.
How big is the ControlBoard PCB?
The ControlBoard measures 250 × 150 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ControlBoard?
170 components, from 43 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 ControlBoard design files?
From the datacrystals/TractionInverterV3 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 ControlBoard design in my own project?
The repository has no license, so all rights stay with datacrystals. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ControlBoard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
