A dual channel brushless motor controller based on the RP2040 microcontroller
The boards cost between $15 and $40 each depending on version and quantity.
NOTE: This design is still changing. There is currently one board version in
this repo. This is our dual CPU version with CAN bus and extra connectors for
our robot. This version also improves the current measurement circuit compared
to the first rev.
Once we have verified the improved current measurement circuit, we will also
support a single CPU version which is smaller and slightly cheaper. This will
look similar to our first prototype version shown in the top of the photo at the
bottom of this document. To view the files for that board see this commit:
https://github.com/Twisted-Fields/rp2040-motor-controller/commit/ceeeb0ee0d24856a9ad8b6b036be5baf15e3ead6Warning These files are still under development and undergoing testing. While we do aspire to produce a design that others can easily fabricate, we do not yet recommend making them for yourself! Please post questions on board status to our community forum at community.twistedfields.com.
Our dream is that you will fab your own boards, make changes, and share your work - giving this design life beyond our efforts.
Designed by Taylor Alexander for Twisted Fields, for the Acorn Precision Farming Rover.

Questions
How big is the Driver module PCB?
It measures 68.8 × 36 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Driver module use?
118 parts, built around the EG3113, INA240A1D, TPS7A1601DGNT and CDBU0130R-HF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Driver module KiCad files?
From the Twisted-Fields/rp2040-motor-controller repository on GitHub, at the commit this page was made from: the board is driver_module/driver_module.kicad_pcb and its schematic RP2040_base/RP2040_base.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Twisted-Fields before reusing the design.
