• Compact design, fitting on the back of a NEMA 17 size stepper motor (41.8 mm x 41.8 mm)
• Incorporates the Trinamic TMC2208 with dynamic microstepping for very smooth operation
• Driver delivers 2 A current (peak)
• New upgraded 328PB MCU from Microchip
• 12-bit encoder (0.088 degrees resolution)
• Drive current is software controllable
• 15 I/O
• 6 Analog, 7 PWM
• 2 x SPI , 2 x UART, 1 x I2C
