Hardware

The hardware seems to be based on the Stormlink SL-2312 SoC, which is a special-purpose chip for NAS applications based on the Faraday FA526 ARM CPU core.

Serial Console

If you look at the PCB, you can actually determine the footprint of an unpopulated 9pin Sub-D connector, labelled COM1. This is actually the serial console (RS-232) port of the device.

However, the level shifter from 3.3V SoC IO Voltage to the RS-232 levels is also not populated. The precise type is unknown, but given the size and pinout it should be possible to find a compatible type. The footprint is marked U19, and the required capacitors for the charge pump are actually placed on the PCB.

If you want to get the serial console working, you either find and populate U19 and COM1, or you solder some wires directly to the 3.3V side of the U19 solder pads. The pinout is as follows: 

1-8 unknown
9  +3.3V
10 GND
11
12
13 RxD out (3.3V)
14 TxD in (3.3V)

On the image, the top right pad is 9, the bottom right pad is 16.

The default console speed is 19200 bps.
