With each new releases of the CEC firmware and CEC Nextion firmware, Ian KD8CEC provides constructors with 2.4″ and 2.8″ versions of the NExtion firmware. Meanwhile, a bunch of other Nextion screen users eagerly await adjustments to the firmware that will work with their particular screen size (3.2″, 3.5″, 4.3″, 5″ or 7″). Adjustments have to be made for each screen size.
Darren VE3XLT has helpfully converted the current beta for the larger 3.2″ screen.
