Bidi Board - Bidirectional DC Motors

The Mini-Transistors range is an economical series dedicated to controlling low-power, low-voltage actuators such as LED strips or small motors.

Dimming & Reversal

The Bidi board is specifically designed for controlling DC motors. It allows you to vary their rotation speed (via PWM dimming). It is especially useful for easily reversing their rotation direction.

It is a daughterboard that connects to one of our Control Boards:

• 8 Midi Actuators with 128-step Dimming;
• 32 Midi Actuators with 128-step Dimming;
• 8 DMX Actuators with 256-step Dimming;
• 8 HD Midi Actuators with 128 or 16000-step Dimming.

Connection to Interface-Z Motor Board
Connection to the 32-Actuator control board, direct connection of 3 motors on the output.

Connection with Bidirectional Terminal Block Adapter
Connection to the 8 HD Actuators control board, connecting a motor via a Bidirectional Terminal Block Adapter.

Technical Specifications

Maximum current: limited to 2 Amps per output, 1.5 A as a precaution.
Therefore, you need to check the motor consumption when running with a load, as this increases the current drawn compared to the motor running idle.

Maximum voltage: limited to 12 Volts. The motor power supply is connected directly to the Bidi board. It is shared by the four motors connected
