Taking a break
We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018.
The MD04 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 15khz. Maximum voltage on the H-Bridge is 60v allowing Motor voltages up to 24vdc.
Control of the module can be any of:
- I2C bus, up to 8 MD04 modules at unique 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 on board filter means you can use a 0%-100% 20khz or greater instead of analogue
- Serial communication at TTL (5V) levels
The MD04 is a medium power motor driver and is an upgraded replacement for the MD03, the main features are ease of use and flexibility.
