Robot MarketPlace - 4QD DMR-203 Radio Control Interface

This is the unit that you would use to go between your standard Futaba/JR/etc radio receiver and your 4QD speed controller. It will proportionally operate two controllers from two channels of your reciever or other standard Pulse Position Modulated (PPM/PWM) inputs.

Applications include

• Robot Wars
• Remote controlled Golf Caddies
• Model Railways
• Model Tanks
• Other applications where powerful motor control via radio is required.

The software implements Dead-band areas on both center and full stick positions and Signal Validation and Rejection routines for noise immunization.

The unit includes opto-isolators at the input from the radio control receiver to minimize problems which can otherwise occur from motor noise etc.

Features
• Dual Channel Radio Control Electronic Speed Control utilizing RISC AVR Micro-controller technology.
• 128-State PWM (Pulse Width Modulated) Proportional Output with Reverse Drivers.
• Mixed or Tank Style Steering modes.
• Configurable Zero Output Failsafe System.
• Switched or Proportional Output Modes.
• Signal Validation and Rejection for Noise Immunization.
• Low Power Consumption.
• Failsafe system that can bring the system to a safe state.
• Compact and Lightweight Design.
