I know 3310 LCD is the cheapest graphic LCD one can buy, but the effort to display something is too much relative to the result (B/W bitmap).

Next best solution is the Nextion 2.4" at about 15 euros, 65536 colors, 4MB memory, 320*240 and touch with RS232 control.

No MCU load to control the display and feedback with touch (no hardware buttons etc).

Richard did an exceptional job on 3310 but is it worth anymore with the cheap smart displays?
