It is commonly sold by various resellers without an identifiable original manufacturer name printed on the PCB. A basic mipi-dbi-cmd[1] script to get the display running looks like this: $ cat st7789v-tft28.txt command 0x11 delay 120 command 0x3a 0x55 command 0xb2 0x05 0x05 0x00 0x33 0x33 command 0xb7 0x75 command 0xc2 0x01 0xff command 0xc3 0x13 command 0xc4 0x20 command 0xbb 0x22 command 0xc5 0x20 command 0xd0 0xa4 0xa1 command 0xe0 0xd0 0x05 0x0a 0x09 0x08 0x05 0x2e 0x44 0x45 0x0f 0x17 0x16 0x2b 0x33 command 0xe1 0xd0 0x05 0x0a 0x09 0x08 0x05 0x2e 0x43 0x45 0x0f 0x16 0x16 0x2b 0x33 command 0x36 0x00 command 0x29 command 0x21 $ mipi-dbi-cmd st7789v-tft28.bin st7789v-tft28.txt Tested on a Raspberry Pi 4B using the panel-mipi-dbi driver.
