Our custom designed PCB for the STM32L452 in the Feather format design
We added a charging circuit for a LiPo, but didn't test it previous to release. If you want to use the charging circuit please check the design for yourself and make sure nothing bad can happen. You have been warned!
We designed this board as a coprocessor for Marlin to control the onboard servo motors but also with a future use as an autopilot for roBOOTer.
To keep the production cost low we chose the same STM microcontroller used throught our boats already.
- STM32L452RET chip
- USB-C connector for power supply and programming connection
- Additional programming header, simmilar to the one used throught our PCBs (usually not populated)
- DFU/programming jumper, to choose the chip mode
- Micro SD card slot to store/read data
- Status LEDs for power, charging, CAN and Timer usage as well as additional, free programable ones
- Access to CAN interface
