The MD03 is a medium power motor driver, designed to supply power beyond that of any of the low power single chip H-Bridges that exist. Main features are ease of use and flexibility. The motor's power is controlled by on-board Pulse Width Modulation (PWM) generators driving the H-Bridge Transistors. Full MD03 Documentation Voltage - 5v logic supply and 5v - 50v for the motor Current - 50mA Max for logic and up to 20A for the motor Control 1 - 0v - 2.5v - 5v Analogue for Reverse - Stop - Forward Control 2 - 0v - 5v (or PWM equiv.) with separate direction control Control 3 - RC Mode - Controlled by standard Radio Control system. Direct connection to RC receiver. (1mS - 2mS pulse with 1.5mS center off). Control 4 - I2C Interface, full control, acceleration and status reporting. Up to 8 modules on bus. SCL speed up to 1MHz Current limiter - Preset at 20A Temperature limiter - Reduces power gracefully if module overheats Size - 113mm x 52mm x 30mm
The MD22 is a robust low/medium power motor driver, designed to supply power for two motors Full MD22 Documentation Voltage - 5v logic supply and 5v - 50v for the motor Current - 50mA Max for logic and up to 5A for each motor Control 1 - 2 independent channels of 0v - 2.5v - 5v Analogue for Reverse - Stop - Forward Control 2 - 0v - 2.5v - 5v Analogue for Reverse - Stop - Forward with second channel for steering. Control 3 - RC Mode - Direct connection to RC receiver. (1mS - 2mS pulse with 1.5mS center off). Control 4 - RC Mode - with the first channel controlling the speed and second channel for steering. Control 5 - I2C Interface, Up to 8 modules on bus. Two modes of operation, direct control of motors or the ability to send a speed and a turn command. Size - 110mm x 52mm x 25mm
Designed to work with our EMG30 gear motors, the MD23 will drive two motors.Controllled by the I2C Interface, you can have up to 8 modules on the bus. Two modes of operation, direct individual control of the motors or the ability to send a speed and a turn commands. Full MD23 Documentation Voltage - 12v only. The 5v for the logic supplied from an on-board regulator, 300mA available for your own circuits. Current - Up to 3A for each motor. Encoder - Processes quadrature encoder inputs from motor. 360 counts per wheel turn when used with the EMG30.Size - 110mm x 52mm x 25mm
