Great prototyping device at a great price
This bit of kit is an enabler for all those who either have low level microprocessor development back grounds but no access to the kit anymore or those that are brand new to the fun and games. It is a well made piece of kit that, as far as I can tell fully conforms. Good stuff!

Nice product
Works well and has compatibility with all the extras which assist with connectivity. Well made and included the cable to connect via USB. Nice board. Leonardo is catered for within the Boards offered by the Arduino when downloading sketches.

Supported by all programs I've tried
Wasn't expecting it to work with official software but it does! I bought this to mod a item I own and I've had no issues with it so far and I've been using it for more than 6-7 months now. In conclusion 10/10 product would recommend.
