We have a new motor control board that is currently being tested and we aim to make this available very soon. The board is based on an RP2040 microcontroller and works as a Raspberry Pi hat. It has support for 4 motors, 2 high-current PWM channels to control LEDs (RP2040 can run PWM at up to 1MHz so there should be no flickering) and a USB-C plug instead of a micro USB. The Pi GPIO connection also connects to SWD on the chip so we can flash the board from the Pi with no user interaction. All unused/extra IO is available on an extension header so it is easy to build shields for the board (I’ve done one to control a Nema17 peristaltic pump). The current version also has a constant current driver we are experimenting with to see if it works better than simple PWM (TP61060). The design files can be found at Filip Ayazi / sangaboard-rp2040 · GitLab .
Currently, it looks like we can sustainably sell these for around 25 GBP, with the exact price depending on the scale of the order. If we scale the manufacturing order correctly and process a lot of orders at once, we can bring the cost down further. To help with this below is a form where you can express interest in buying a sangaboard. Anyone who fills in the form will be contacted directly when the boards are available and will have the option of buying the Sangaboard at a lower price.
TLDR: Sangaboard v0.5 coming soon, form above if you want some
