Based on ATMEL Official STK500 USB AVRISP CH AVR ISP high Speed Programmer Compatible with at AVRISP from ATMEL Supports AVR Studio 4/5/6/7 ISP_6PIN Interface @XYGStudy

Features
Resolution
* Using the same MCU and core circuit as AT AVRISP, easy to use, stable and reliable
* Based on ATMEL official STK500 firmware, identified as AVRISP/STK500 in AVRStudio, high speed programming
Standard ISP_6PIN connector
CH340G USB to UART converter, supports most popular OS, including WIN10, more stable, faster programming
Supports AVR Studio 4/5/6/7
Supports 0~ 3.6864MH z frequency output (via the two through holes on the backside, round=GND, square=PCLK, frequency is configurable by software)

Supported Software
AVR Studio or WINAVR (GCC) is used as front-end software
Supports files generated by IAR, ICCAVR, CVAVR, etc.

Performance
High speed programs FLASH ROM, EEPROM, Fuses, and Lock Bit
It takes only 5.5 s to program a 45K program file with verification (the test MCU uses 8MHz external crystal, and programming speed is set as 1.8MH z)

Connects to PC
Uses a quasi-USB interface (USB To COM)
The COM port is configurable, a PC could connects to several USB AVRISP CH at the same time
Note: the COM port should be configured as COM1-COM4 for the first time, refer to the user manual for more details.
