JTAG-Serial Info
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.
