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

Unlike every other AVR programmer I've used before, this programmer DOES NOT POWER THE BOARD. The VCC pin provides no power. So if you want to use this to program anything you have to power the board externally, which is inconvenient at best....Unlike the STK500, this board also DOES NOT DO HIGH VOLTAGE PROGRAMMING. In other words, if you are trying to recover a chip with badly set fuse or lock bits, this programmer can not do that. It does not provide the necessary 12V on the RESET pin.This board is a CH340 USB<->Serial converter, with an Atmega8535 chip and s shift register (somehow?). There is no power supply or any other supporting circuitry on this board.So basically this is pretty much the worst AVR programmer you can buy. It does nothing it claims in the description and is far worse than any of the TinyISP or other type devices."Based on ATMEL Official STK500"???!??!? LOL ....Stay away!

Worked great on programming custom atmega.Able to add the tool on Atmel Studio 7.

My STK500 died and I didn't feel like spending $150 for a new one, so I decided to try this thing. I'm using Windows XP, SP3. My Studio 4.19 recognized the device, no problem. But, when I went to the Fuses or Lock Bits tab, it would not talk to the unit. The green LED flashed red then green.I lowered the ISP frequency to 4.00kHz and was able to read and program both the Fuses and Lock Bits (good!). However, when I went to program the Flash, it gave me an error stating that the minimum ISP frequency must be 5kHz or higher (picture 1).Studio only has 5 frequencies from which to choose (picture 2). 57.6kHz was the next highest from 4.00kHz. When I selected that, the device tried to program, but failed verification. And again, with 57.6kHz, I could not read the Fuses or Lock Bits.I tried this on 2 different XP machines (Studio 4.19 and 4.15) and several target boards.I've sent 2 emails to Waveshare and did not get a response. So, I sent it back and may try another device.

Good first impressions. Works out of the box and is as advertised.

Unable to configure to be detected by either AVRDUDE or Atmel Studio 7. Have set to different Com ports, changed Baud rates and reloaded drivers but device remains invisible to system although I can see it listed in the Device Manager and assigned Com6.

I got a quick delivery and a good product.

works perfectly with atmel studio 7 on windows 10
