K3NG Universal Rotator Controller Kit

Description

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

Universal K3NG Rotator Controller

Skill level required: Advanced    –   Not suitable for beginners

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

Sorry, I cannot offer personal assistance to teach you how to use Arduino/Teensy/Nextion
Lots of on-line resources are available to help you – Google!

This K3NG based computer interface controller board suits a Yaesu G-5500 dual azimuth/elevation controller and also accommodates various other configurations, such as a azimuth only rotator along with a linear actuator for elevation. 

Also features PWM derived speed voltage control output (ie; Yaesu G-800DXA etc), i2c remote sensors input via bus extender, a PWM interface for external PWM carrier driver board, and easy access to 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.

• PCB  132 x 55mm, M3 mounting holes

• Accommodates Teensy 3.2 MCU (not supplied)

• Nextion (not supplied) touch screen HMI interface

• Generic rotator control with CW/CCW/Up/Down outputs

• Yaesu G-5500 compatible

• Yaesu G-800DXA (and G-1000-DXA, G-2800-DXA) PWM speed voltage output

• Azimuth & Elevation analogue potentiometer input
