... STK503 User Guide Introduction STK503 is a top module to the STK500 development board from Atmel Corporation. It adds support for 100-pin AVR microcontrollers (ATmega2560, ATmega1280 and ATmega640). STK503 includes connectors and hardware allowing full utilization of the features of these devices, while the Zero Insertion Force (ZIF) socket makes it easy to use TQFP packages for prototyping ...
