    Very excited as this is such an affordable bit of kit that is has been out of reach for many casual hobbyists. Assembly can be intimidating as there are surface mount resistors to solder, requiring some skill. Some other variants of this kit may have the SMDs pre-soldered. Also resistors are difficult to identify due to their size so must be carefully measured before soldering. Soldering the 40 pin connector to LCD is also a challenge. Instructions provided were good and contains plenty of pictures to illustrate assembly. Troubleshooting flowchart also clear and helpful. The kit requires great care in soldering so definitely not for beginners, however with a little patience and courage (on my part) can be extremely satisfying to get working. Good value however no instructions on connecting through on USB port / UART which I assume enables data logging.

    All kit arrives In the process of making the kit. This is my second kit and I failed to slide the small pads correctly resulting in the pads coming away from the board. Yes I could bypass this but I also wanted to spend time running experiments so I ordered another. I'm hoping to be successful this time
