 It is the NeoPixel Driver BFF for QT Pi and Xiao boards. This gives you level shifted 5 volt logic and a really nice easy JST connector for plugging in your NeoPixel strips. You just attach this to the bottom side of a QT Pi or a Xiao board and you are off to the races lighting up your NeoPixels. So I just picked some color matched headers there so that I could plug that in and know that everything was in the right orientation. So only can plug in one way. That's a keyed connection there. And then I'm going to simply plug in a USB-C cable. This is going to a powered hub on my computer. And you can see there I'm lighting up some NeoPixels, lighting them away. That right there is my product pick of the week this week. It is the NeoPixel Driver BFF for QT Pi and Xiao boards.
