The “Remote Head Unit” gives you a larger remote touchscreen that will allow you to tuck your hotspot away in a car (or at home). This is accomplished using a
2.8″ (Currently shipping a 3.2″ screen)Enhanced Nextion touchscreen display and the popular PD0DIB layout (used with permission).
I will install the necessary drivers to allow the screen to work properly. I will then also configure the hotspot to work with the screen. When configured to work with the screen, the built-in OLED screen is not used. However this is a very simple setting to change if you wish to switch back!
