Dual TMC2660 Expansion Board
A 70x78mm expansion board providing two 2.2A (RMS) / 2.8A (RMS) boost current, powered from 9-35 volts DC and providing a STEP/DIR/EN and SPI-based interface.
Prototype
Features:
- Two independent TMC2660-PA steppers
- Experimental 2-layer (1oz copper) design
- Relatively large PCB to support proper thermal dissipation (70x78mm)
- 1 on-board 100k NTC with a 4.7k bias
- compatible with 3.3V or 5V electronics
- 18-pin 2.54mm DIL Header with 1 ADC (thermistor), 2 sets of STEP/DIR/EN, and SPI. (I2C unused: for future use)
