| K101-MM2BA02-A panel | No |
| Sandisk sdinadf4-32g EMMC chip | Yes |
| GalaxyCore GC5025 Back camera | No |
| GalaxyCore GC2365 Front camera | No |
| MT6328 PMIC | No |
| MT6625L BT/Wifi chip | No |
| MT6169 maybe LTE | No |
| MT6158 RF | No |
| NTC3201 Temperature sensor | No |
| GSL3676 touchscreen chip / CY101S200-01 touch panel | No |
UART
On the board, next to the reset button, there are 4 pins: Tx1, Rx1, Tx0, Rx0. With Tx0 I was able to get the bootloader messages. Listen at a speed of 921600
Size of UART pins. Use thin copper wire and connect to Tx0 Rx0.
Mainline status
Still in its infancy. Simple-framebuffer and UART partially works. https://github.com/mt6735-mainline/linux
