K3NG G-5500 Rotator Controller Kit

Description

*** Discontinued – Teensy 3.2 no longer available ***

G-5500 K3NG Rotator Controller

Skill level required:  Intermediate – Advanced    Not suitable for beginners

Familiarity with Arduino IDE, Teensyduino & programming MCUs via USB
Familiarity with Nextion programming via microSD card or USB/FTDI
Soldering connectors/wire
Mounting Nextion and board in your own enclosure

This K3NG based computer interface controller suits a Yaesu G-5500 type dual Az/El rotator controller for operators who want a practical and powerful interface, along with the ability to access spare MCU I/O ports for future experimentation.

Pre-assembled and tested (factory MCU removed after testing) and ready for you to complete the integration into your own system requirements.

• Yaesu G-5500 compatible for CW/CCW/Up/Down control

• PCB 100 x 50mm

• Accommodates Teensy 3.2 MCU (not supplied)

• Nextion (not supplied) touchscreen interface (free Nextion firmware by VK4GHZ)

• Generic azimuth only rotator control compatible

• Az and El analogue potentiometer inputs

• Piezo audible alert output

• Teensy Real Time Clock battery connection

• 4 x N.O. generic push-button switch inputs with pull-ups  ie; as remote CW/CCW/Up/Down control lines

• GPS serial data pass-through (genuine FTDI chip) to USB Mini-B for time-syncing PC

• High efficiency DC-DC Buck 7805 Regulator

• Powered from G-5500 Controller

• Accommodates MT8870 DTMF decoder module (not supplied) for remote DTMF control applications
