This auction is for STK128+ Standard

Development Board Designed for ATmega128, With 1 piece of ATmega128 Device Board

Overview

The STK128+ is a complete, cost-effective development board for the ATmega128. It is designed to give designers a quick start to develop code on ATmega128 MCU and makes them develope prototype device easily.

The ATmega128 chip is mounted on a device board, which can be separated from the mother board. Hence, easily changing MCU is supported. The ATmega128 chip is in TQFP64 package and will randomly be ATmega128-16AU or ATmega128L-8AU or ATmega128A-AU.

The STK128+ Standard package comes with an ATmega128 device board, while the STK128+ Premium package comes with the standard package, an additional spare ATmega128 device board, an Experiment Fittings Pack.
