Further information
The information on this page was mainly obtained from BoxMatrix. That website also contains (copyrighted) PCB pictures. There's also a video/discussion of this disassembly on Youtube.

A modification kit with a case extension, RP-SMA pigtails and a pair of external antennae is available from Frixtender. That site also has additional PCB pictures.

Pin headers, JTAG and UART ports
Warning: Be extremely careful when disassembling the device and connecting to pins. The lower PCB is connected to mains, only lies loosely on top of two metal spring contacts that directly expose mains voltage. This means that even a minor misalignment of the PCBs within the back/lower half of the plastic casing could result in shorting out mains power, destroying your device or giving you a life-threatening electric shock.

  The unpopulated 4-pin 0.1" THT pin header next to the LAN port is a UART console to the Eva_AVM bootloader console that uses a voltage of 1.8V, a baud rate of 115200 and the following pinout: [o] VCC (do not connect!) (o) RX (o) TX (o) Ground   The unpopulated 10-pin JTAG-like SMT pin header has not been tested thus far.
