MD14 - 24Volt 5Amp H Bridge Motor Drive
Devantech
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
