I was fed up keep wiring up messy boards so i put together a simple setup where any sensors could be experimented on with a quick and easy setup. It also has a charger and battery with 5v boost so it is completely portable. Charger booster is from a cheap poundland powerbank, it has the added use of a usb 5v out as well as the micro charge in port. I am using a flat 3.7v battery but an old phone battery would do just as good. Enjoy I do all this work for no profit , please view my grandsons first ever song he wrote ans sung on holiday, you will be touched. https://www.youtube.com/watch?v=ZdpMYMSmIr0&t=30s

Update, Job done, 5v on bottom rail and 3.3 on top rail, Soldered underneath
