Beelink X2

The Beelink X2 is an inexpensive TV box/multimedia player based on Allwinner's H3 SoC.

Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

Sunxi/Legacy U-Boot
Use the  build target.

Mainline U-Boot
Use the  build target.

Sunxi/Legacy Kernel
Use the  file.

Mainline kernel
Use the  device-tree binary.

= Tips, Tricks, Caveats =

The X2 is configured to boot from µSD first, so testing an alternative OS is simple. Linux images built for the OrangePI mini 2 can be booted, but provide incorrect GPIO assignments for at least the power LED.

FEL mode
The button on the bottom of the PCB triggers FEL mode (to be confirmed). It is reachable through a small hole in the bottom plastic cover. The X2 does not provide a USB OTG port, but the USB port next to the power socket can be used with a male-to-male type A USB cable. This will also provide power to the X2.

= Adding a serial port (voids warranty) =



The X2 UART runs at 3.3V levels, so you need a level converter (e.g. MAX3323) to connect the board to a regular serial port. Alternatively, a USB-to-UART adapter with 3.3V levels will also work. See the UART howto for details.

Device disassembly
The case is clipped together using plastic tabs on all four sides. Please see the Plastic tool howto for details of opening cases like these. The PCB is held in place by four small Philips-head screws. Make sure to remove the µSD card before taking out the PCB. The H3 chip is attached to an internal heat sink using a thermal pad.

Locating the UART
The UART (3.3V levels) is available on four solder holes (2mm spacing) next to the µSD slot. Soldering in a header will void the warranty.

With the square pad as pin 1 (i.e., counting from right to left in the photo), the pinout is as follows:


 * Pin 1: (tbd)
 * Pin 2: (tbd)
 * Pin 3: 3.3V
 * Pin 4: TxD
