Treedix Breakout Board Module with Pin Board for Teensy 4.1/3.5/3.6 Compatible with Arduino

Got it and had my new Teensy 4.1 mounted in about 15 minutes. It does take some soldering, of course but the pads solder easily. Disregard the comments about needing little red wires!! I think that photo is just showing that those pins are connected together. Each of the Teensy pin mounting points are directly connected to pin mounting points for the solder on screw terminals through runs on the board. No need for anything that's not in the kit - other than a Teensy, of course. As far as comments about the size of the terminal screws - yes, they are small, by necessity I'm sure. I have a jeweler's screwdriver set and and there are at least two screwdriver tips in it that fit the screw slots. If you don't have a set, get one!!

Had to solder it together but expected that, had to solder the pins on the teensy so did both in 1 shot.

Awesome solution for teensy, the terminals are little to small but is good for the price.

A previous review complained about the vendor not supplying the "Little Red Jumpers" as illustrated in the product page. That picture is somewhat misleading because where they show the jumpers there is a trace running between the two involved pads, all 48 pairs. The traces are a little difficult to see because of the black coating. Tilt the board a little under a light and they are easily seen. A quick check with a multimeter will also verify all 48 pairs are connected. As for the "tiny" screws on the green strips, just about any jewelers screwdriver set will have the 3/64" tip.

First picture shows a fully assembled one but that's not how it comes and I have no desire to spend hours of my time soldering it up. Returned
