== Mounting Target Board ==
The selected target board (AVR or XMEGA) should be placed onto the main victim area. See the [[CW308 UFO Target]] page for details.
The oscilloscope should be set to AC-coupled mode to eliminate the constant DC offset.
== USB Serial Usage == A serial connection is needed on GPIO1/GPIO2. This can be provided by any 3.3V USB-Serial cable (DO NOT use a cable which outputs either RS232 levels, or 5V levels). [[File:P1090080.jpg|600x600px|Details of a possible oscilloscope connection on the trigger pin, along with a USB-serial on GPIO1/GPIO2.]] This can either be connected at J1 (the 20-pin ChipWhisperer header), or the pin headers directly beside the victim board. The pin headers do not provide diode clamping, where as the connections at J1 have diode clamping.[[Category: CW308 Targets]]
