 The Trinkie QD2040 is a USB key and a QDRP2040 all-in-one. I have a magnetometer plugged into it over the stem of QTI squared C and then I'm going to go ahead and plug it into a hub that's plugged into my computer. I'm going to run Python code on the computer that is then using the USB connectivity of the Trinkie to access the sensor here. So if I take a magnet and go ahead and move it towards and away from that little magnet sensor you can see I have the values changing in the little terminal there as well as the NeoPixel that's built onto the Trinkie updating and increasing its brightness or decreasing its brightness. So that is one really cool way that you can use the Trinkie which is as a sort of go-between for your Python on your computer to talk to circuit Python-based devices. It is the Trinkie QD2040.
