Supports files generated by IAR, ICCAVR, CVAVR, etc.AVR Studio or WINAVR(GCC) is used as front-end software.You will see “Done burning bootloader” at Arduino IDE when it is done. It will take awhile to burn (but still faster than USBasp ).During burning, you will see the “BUSY” Led flashing.Then click “Tools” -> “Burn Bootloader” -> “w/ USBtinyISP” to start burning Arduino bootloader Under the list of “Tools”->“Board”, choose your Arduino version. After the hardwares are connected, we can start the Arduino IDE.Then connect AVRISP to computer by USB cable (A to B type). Connect programmer and ICSP of Arduino with the 6-pin cable adaptor included.Choose the programmer to be AVRISP MKII in tools>programmer of Arduino IDE.2 LEDs to indicate 'USB/Power good' and 'Busy'.Supports 0~3.6864MHz frequency output (via the two through holes on the backside, round=GND, square=PCLK, frequency is configurable by software).CH340G USB to UART converter, supports most popular OS, including WIN10, more stable, faster programming.Based on ATMEL official STK500 firmware, identified as AVRISP/STK500 in AVRStudio, high speed programming.Using the same MCU and core circuit as AT AVRISP, easy to use, stable and reliable.
