Motor Controller MD04 Motor Driver Onboard Pulse Width Modulation PWM for H-Bridge Transistors

The MD04 is a medium performance motor driver and is an improved version of the MD03. The main features are ease of use and flexibility. The motor power is controlled by on-board pulse width modulation (PWM), which drives the H-Bridge transistors.

Specifications:

• voltage: 5V - 24V
• Current: up to 20A
• Control 1: 0V - 2.5V - 5V Analogue for forward, stop, forward
• Control 2: 0V - 5V (or PWM-Äquiv.) with separate directional control
• Control 3: RC Mode - Controlled by Standard R/C. Direct connection to the RC receiver. (1mS - 2mS pulse with 1.5 ms center off).
• Control 4: I2C interface for full control, acceleration and status reporting. Up to 8 modules on the BUS. SCL speed up to 1MHz.
• Control 5: Serial at 5V and up to 115.2 baud rate.
• Current limiter: stops at 20A.
• Temperature limiter: Automatically reduces the amount of current when the module overheats
• Gröe: 113mm x 52mm x 30mm
