Idea for vendor to make the boards https://www.pcbway.com/
Trim system controller is based on this board:
https://www.rugged-circuits.com/microcontroller-boards/ruggeduino-smalls-tcrmx
Which has the same pinout of this board:
Power supply circuit:
We also need the following:
- (1) DRV8871 Motor controller
- (1) digital pot MCP4651 (not MCP[1|2]XX because those are SPI which needs more pins)
Inputs are:
ADC
- ADC for linear resistor 1
- ADC for linear resistor 2
- ADC 4 for i2c
- ADC 5 for i2c
Digital
- Encoder A
- Encoder B
- Trim up (both up/down goto neutral)
- Trim down (both up/down goto neutral)
- Trim up (both up/down goto neutral)
- Trim down (both up/down goto neutral)
- Motor IN 1
- motor IN 2
- transistor for sinking current to discrete input.
