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 Pulse Width Modulation (PWM) of the H-Bridge at a frequency of 7.8KHz.
The 15V MOSFET drive voltage is generated on board 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.
- Motor voltage, anything from 5VDC to 50VDC to suit your motors.
Control of the module can be any of:
- I²C bus, up to 8 MD03 modules, switch selectable addresses.
- 0V-2.5-5V analog input. 0V full reverse, 2.5V center stop,
5V full forward.
- 0V-5V analog input with separate direction control
- RC mode. Controlled directly from the RC receiver output.
- PWM. A simple onboard filter means you can use a 0%-100% 20KHz
or greater instead of analog.
This item can be connected directly to a USB port on your computer using the optional USB to I2C Interface Module.
NOTE! The MD03 drives one motor. If you have two motors,
you will need two MD03.
