Richard D
Pricey but excellent display

Good support with Github repositories will help you get up to speed. I used mine as the head/display unit in an RC airplane digital scale, employing ESP-NOW for wireless communications with various components.

Some misalignment between the AMOLED display itself and the bezel that covers the display. This made border lines drawn at the edges of the display appear out-of-square with the physical edges of the device.

Great bargain.

Great little component for electronics learning and experimenting
