Had to order one more for $15 because of this :-)
Also I got the display working with Espruino just few days ago. It has 64 colors - it uses 2 bits for R,G,B = 6 bits total. It uses ST7301 controller, there is no datasheet but got initialization commands from original firmware. It uses similar commands to eg. ST7789 or ST7735 however one pixel data for 0x2c command is only single byte so the transfer is twice faster :-)
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
DK08 is on aliexpress and now for much better price
