Overview
The MD22 is a robust low/medium power motor driver, designed to supply power for two motors. Main features are:
- Drives two motors with independent control.
- Ease of use and flexibility.
- The 15v MOSFET drive voltage is generated onboard with a charge pump, so the module requires only two supply voltages;
- A standard 5V supply for the control logic, only 50mA maximum is required.
- The H-Bridge has a rating of 60v allowing Motor voltages up to 24vdc.
- Steering feature, motors can be commanded to turn by I2C register or input (Analogue + Servo).
- Control of the module can be any of;
- I2C bus, up to 8 MD22 modules, switch selectable addresses and 4 modes of operation including steering.
- 2 independent 0v-2.5v-5v analog inputs. 0v full reverse, 2.5v center stop, 5v full forward.
- 0v-2.5v-5v analog input for speed ,with the other channel for steering.
- Independent channel RC mode. Motors are individually Controlled directly from the RC receiver output.
- RC mode with steering, allows speed control with one stick of radio control, and steering with the other.
- Uses high current MOSFETs, making a very robust module.
MD22 Connections
The Motor Ground and the Logic Ground are internally connected on the Module. Be sure to use cable rated for at least 10A for the Battery, Fuse and Motor leads.
