Placing an ATmega169 on the STK502

STK502 contains both a ZIF socket, and a footprint for a TQFP package which allows an easy way of soldering an emulator adapter directly into the STK502. Care should be taken so that the device (or adapter) is mounted with the correct orientation. The Figure 1 shows the location of pin1 for the ZIF socket and the TQFP footprint.
