Das87 DSM2 7CH PPM Transmitter is an AR6100 type receiver reprogrammed to be a DSM2 compatible short range transmitter. It is intended to be used as a 7ch TX ‘module’ with an older transmitter or any DIY RC project with PPM signal out. The TX accept idle high and low (normal and inverted PPM).
Das87 DSM2 7CH PPM Transmitter is a DSM2-compatible transmitter module intended to convert traditional joystick transmitters to 2.4GHz. It is a ‘DIY’ solution requiring some understanding of electronics and soldering. It may require a voltage regulator and Zener diode to control voltages from the host transmitter. The host transmitter can have 2 to 12 channels. The first 7 PPM pulses will be transmitted. To use as a module you will need a 3.3 or 5v regulator if it is to be powered from 2S or 3S Lipo. Some PPM signals exceed 3.6v so you may need a 3.3v Zener diode and 1000 ohm resistor to limit the voltage.
The TX moudle can be powered by 3.2-10v
The PPM input to the signal Pin7 must be 2.1v to 3.6v (max) when high
The PPM input must be below 0.8v when low
Pin7 ‘floats’ needs active (strong) highs and lows
The PPM signal can idle high or low
1. Switch the Rx on in bind mode.
2. Put bind plug on Tx1 Pin1.
3. Switch Tx1 on.
4. Wait for Tx and Rx led to stop flashing.
