## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works perfectly
  

*by A***X on Reviewed in the United Kingdom on 23 November 2022*

This is a very reliable programmer. I had a lot of failures with a few Chinese programmers. But since I use this programmer, those problems are over.

    Seems good but setup guide would be useful
  

*by J***N on Reviewed in the United Kingdom on 28 March 2021*

Tried this out the box with a spare ATTiny85 initially, installing software from Pololu website, but realised that the driver with the "AVR Development bundle" or maybe config utility does not work with this programmer properly.Took some poking around and uninstalling the bundle and reinstalling with v2 software and drivers for Windows (9mb MSI), but then the configuration utility did pick up the board. Need to set regulator mode to 5v and VCC output to enabled (unless chip has external/different power source), but after that worked straight away in Arduino IDE with programmer set to Atmel STK500 dev board. Haven't tried in anything else yet but if works in one IDE then should work in all.Recommended but may need to look up a bit of extra info as no instructions with device and those on website are not great. Make sure to download the V2 Software and Drivers from the manufacturer website rather than bundle as config utility in the bundle does not work (with Windows at least).

    Works brilliantly - but should be included with the 3pi as its essential, not an option!
  

*by D***H on Reviewed in the United Kingdom on 31 October 2020*

Ok so these are great, it works as it should do. My only real gripe is this should have been included with the 3pi. As the 3Pi is useless without it. Luckily I managed to get a 3pi on clearance at £20 so £12 more for this isnt too much of a sting. But with good quality chinese robots that have everything and do more than the 3pi running at aruond £50+ (see elegoo for example) this makes the 3pi and this interface at full price not a good purchase. If you wish to add bluetooth and ultrasonics to the 3pi then you had best get a second mortgage as you will most likely hit another £80 easily.Dont get me wrong the 3PI and this interface are high quality products, but they are simply over priced for what they can do out of the box. e.g. unable to program the 3pi without this interface, no ultrasonics (without another hefty purchase of multiple parts) on the 3pi, no bluetooth (without another hefty purchase of multiple parts and boards) on the 3pi.
