Can I use this controller with a raspberry pi to control the Maxarm, I got a 2nd one, but the esp32 controller doesn't work. It was used and not put together correctly by the prior owner.
Hello,
When controlling the MaxArm using a Raspberry Pi and STM32 chip, there are no specific tutorials available. You may need to conduct your own research to explore and implement the solution
-
Is there pre-installed firmware on the board or will we need to flash it onto the board? And is the code and schematics for the board available as open source resources (since there is no documentation or repo linked here)?
Yes, the board comes with the firmware pre-installed. To access the code and schematics, please use the following link: https://drive.google.com/drive/folders/1XBL2pdDXOVoiNNGgitFoBGrAt86nP8Ex?usp=sharing.
