单片ATmega8实现USB接口的STK500 V2，ATmega8内建USB的CDC类和HID类，通过硬件切换CDC类和HID类，支持高压编程，在AVR Studio 中直接使用。使用CDC类时在电脑中虚拟出一个通用串口。

AVR-Doper

Features

• HVSP allows using RESET pin for I/O, which is especially beneficial on 8 and 14 pin devices.
• Simple hardware which can be built on a single sided PCB. No special USB chips are needed.
• Compatible to Atmel's STK500 with built-in USB to Serial converter.
• Adjustable ISP clock allows flashing of devices clocked at very low rate, e.g. 32 kHz.
• ISP clock can be lowered with a jumper (if the programmer software does not support setting the ISP clock).
• Second USB to Serial converter for processing debug output from the target.
• HVSP connector compatible to HVProg, another STK500 compatible programmer (see www.der-hammer.info/hvprog/index_en.htm).
• Open Source (including firmware and schematics).
• Uses USB power supply, no external supply required.
