    Description The DMR-203 is a general purpose dual-channel radio control interface providing proportional motor speed control from a standard radio control system e.g. Spektrum, Futaba etc. It accepts two standard PPM inputs from the RC receiver and converts these to a suitable signal to operate two of our controllers, such as the DNO, PRO or 4QD ranges. Applications include - Robots - Model railways - Model tanks - Remote controlled vehicles - Special effects - Other applications where powerful motor control via radio is required. Features - Mixed or tank style steering modes. - Dead-band areas on both centre and full stick positions. - Configurable failsafe system. - Switched or proportional output modes, with reverse drivers. - Signal validation and rejection for noise immunity. - Inputs optically isolated. - Low power consumption. - Compact and lightweight design. - Supplied with connectors and cable as diagram. Suitable Controllers The DMR-203 may be used directly with - 4QD DNO - 4QD VTX - 4QD Pro-120 - 4QD series - Porter 5/10 by using the diagram below

    Worked well, till it malfunction

    This is a really good piece.(and an Atmel MP controlled) It is highly customizable device. When the device failed(at robo games), it would only wanted to control one side at a time in tank mode. We have not investigated why it failed.
