Assembly instructions

Firmware

For beginners Getting Started with Arduino

You can configure firmware from master tree Arduino firmware by K3NG

Or download preconfigured version

Please read author documentation

Power

The entire module can be powered from USB only, but there is a voltage drop, it is better to use an external +5V source, or a DC/DC converter and cut the power to the attached USB cable.

Pin 3 in CON1 (+5 volts input to supply measure the azimuth)- input stabilized voltage from power board This pin may be short connected (as picture below) with pin4 CON1 (+5 volts to interface), then the voltage measurement uses a common 5V voltage from the power supply module.

Connect DC Rotator (DB15 female) and power inputs

  • Need three jumper
    • short DC position P6 jumper switch
    • short JP1 jumper
    • short PHASE-SW (center) position CON1
  • connect example
    • Yaesu G800
      pin DB15      G800 unit
-------------------------
     1+2  ->  5
     3+4  ->  4
      15  ->  1
      14  ->  2
     GND  ->  3
