VK4GHZ Nextion for K3NG Rotator Controller now gets a version for the NX8048K050 5.0″ Enhanced touchscreen.
The 5.0″ screen is nice!
Below are some comparison shots along side a familiar 3.5″ Nextion.
(5.0″ screen still has protective layer on top of screen, so tends to look dull)

A series of videos demonstrating the VK4GHZ Nextion for K3NG Rotator Controller
Part 1 – Basic Az system
Part 1 looks at a basic azimuth-only system and introduces you to some of the functionality offered.
Part 2 – Elevation
Part 2 introduced elevation functionality and adds a decimal place to Az & El readings.… Read more...
It’s not everyday you come across a project from somebody else that is well documented, relatively easy to pick up and work with, and, has the ability to customise it to your hearts content!
The K3NG rotator controller is one such project. … Read more...
The K3NG rotator controller is extremely well supported by the author, Anthony Good, K3NG.
Since the last bug report, one issue, easily overlooked by those not entirely familiar with the Nextion display, has been identified that can easily cause grief,
Along with creating fonts with iso-8859-1 encoding, make sure when setting up your Nextion HMI project in the Nextion Editor, that the character encoding type is also set to iso-8859-1.… Read more...
The K3NG Rotator Controller project is aimed towards Arduino Mega 2560 or similar hardware.
Standard ADC resolution on many of the Arduino boards is 10-bit, however the Arduino Due, Zero, and MKR family and Teensy 3.x family have 12-bit ADCs.
So if you’re running this hardware, why not make use of the extra ADC resolution with four easy steps;
