According to various Wiki this is
CPU: Qualcomm IPQ8064
Flash: 128MB
RAM: 128MB
BT: TI CC2540
Looking at the Internal Photos provided with FCC documents I assume that the 2x10 pads on the side of the board are ARM JTAG pins and I would suspect a serial console at the 4-pin header or the 5 pads near it.
Maybe folks more familiar with IPQ806x can help you out with the details, I haven't worked with that platform myself. @Ansuel maybe?
