Atmel STK-128 Microcontroller development board


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 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, usb power connector.

  • Power

    • Powered from external 5V power supply

    • Jumper for configuring voltage level to be applied, 5V/3.3V

  • Onboard Chips

    • ATmega128 (TQFP64), MCU, mounted on the device board

    • AMS1117-3.3, on board regulator

    • MAX3232, True RS232 Transceivers

  • Interfaces

    • Two RS232 connector for UART0 and UART1, DB9 standard

      • Guaranteed to operate under 3V level supply thanks to the MAX3232

      • UART0 and UART1 jumpers, short the jumper to connect UART to AVR MCU, open the jumper to vacate the I/O ports.

    • 6-pin / 10-pin ISP port

    • JTAG port

  • Human to Machine Interface

    • RESET button, used to reset the MCU

    • Power indicator LED

    • 8 surface mounted LEDs, can be used as I/O status indicator

    • 8 Push-buttons, for analog input

  • Other Features

    • Crystal configurable, there is a jumper for selecting on board 7.3728M crystal or external crystal mounted via the socket

    • All the MCU pins are accessible on expansion connectors for further expansion

    • All the pins are marked on the board. These marks describe the function of each pin

    • Compatible with several AVR MCUs:

      • Fully compatible with: ATmega64/ATmega128

      • Partly compatible with: ATmega1281/ATmega2561, AT90CAN32/AT90CAN64/AT90CAN128
