DC motor

Dual Bipolar DC Motor Driver


DC Motor can drive 2 DC motors with speed and direction control depending on the CV input. Motor driving circuitry and CV input circuitry are optically isolated without any ground connection. Requires external power supply for driving motors.


  • two-channel bipolar DC motor driver
  • CV circuitry and motor circuitry are optically isolated
  • external power supply for motors required
  • motors are driven directly from power supply
  • bipolar CV input with attenuator per channel
  • speed offset knob per channel
  • directional offset knob per channel
  • maximum peak current 1A, constant current 600mA
  • handmade locally by Bastl Instruments in Brno, Czech Republic
