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.

Features

  • Voltage - 5v - 24v
  • Current - up to 20A
  • 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
  • Control 5 - Serial at 5v levels and up to 115.2k baud rate
  • Current limiter - Preset at 20A
  • Temperature limiter - Reduces power gracefully if module overheats
  • Size - 113mm x 52mm x 30mm
