The ATSTK600 is a comprehensive development and starter kit designed for 8-bit and 32-bit AVR microcontrollers. It enables quick and efficient code development with advanced features for prototyping and testing new designs. The system uses an innovative routing and socket card setup, allowing easy switching between different AVR devices by customizing the routing card for each device, ensuring all I/O pins are directly accessible without altering electrical behavior. It features a USB interface for programming and control, supports powering from USB or an external 10V-15V supply, and offers adjustable target voltage up to 5.5V. Additionally, it provides two high-accuracy reference voltages, a configurable clock oscillator up to 50MHz, and supports various programming methods including Serial ISP, PDI, JTAG, and wire programming for different AVR devices. Suitable for applications in automotive, communications, automation, motor control, security, consumer electronics, industrial domains, sensing, lighting, and metering. The kit includes a power cable, high-speed USB cable, cable kit, screws and nuts, clips, and an MCU card for ATmega2560. Note that specific routing and socket cards for different devices must be purchased separately.
