Main chips
- RK3399 system-on-chip (1)
- LPDDR4 SDRAM (21)
- SPI NOR flash memory (29)
- eMMC flash memory module (26; Note: Some datasheets indicate a low supported number of mating cycles.)
- WiFi/BT module (27)
Mainboard Switches and Buttons
There are two switches on the main board: disabling the eMMC module (24), and enabling serial console UART (9) via headphone jack.
The Reset and Recovery buttons (28): the reset button performs an immediate reset of the laptop. The Recovery button is used to place the device in maskrom mode. This mode allows flashing eMMC using Rockchip tools (e.g. rkflashtools).
