A Yaesu G-5500 (etc)  rotator controller project based on Anthony Good’s popular K3NG rotator controller.

This project features a Teensy 3.2 microcontroller and Nextion Enhanced HMI user interface.

• Az analogue potentiometer input
• El analogue potentiometer input
• Four NO push-button switch inputs with pull-ups available
• Teensy I/O pins available via pads
• 100 x 50 mm
• Powered from Yaesu G-5500 controller

 

G-5500 K3NG Controller Board

• GPS serial data pass-through (genuine FTDI chip) to USB allows for simultaneous Teensy  &  PC time-syncing

 

• High efficiency DC-DC buck 7805 replacement regulator (or use traditional linear 7805 with heat sink)

• Audible Alert (peizo) connector

• Teensy 3.2 Real Time Clock (RTC) battery connector

• Nextion connector

 

• MT-8870 DTMF module pads available for DTMF experimentation
