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!!

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.

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.

The board looks mechanically fine but I had a very difficult time soldering in the headers. There is "gold" plating but I doubt it is gold or if it is the plating process was bad. I have had no difficulty soldering many other boards including tin plated and gold. For the price they should do a better job,

The teensy in the photos is plugged in backwards! VIN is supposed to be next to the USB, not the SD card. When I plugged it in the way shown in this photo, my Teensy stopped blinking, and now it does not even communicate with my laptop at all, even without the breakout board connected. It turns out this is likely due to a design choice. The GND pins are tied together on the breakout board. This normally would be fine if the board is plugged in the right direction. But if you ever plug it in backwards and power it up, several of your GPIO pins will be shorted together, which as I have unfortunately shown, WILL DESTROY the teensy. Had they left all 40 pins isolated on the PCB, this would not have happened, and this danger would have been eliminated. I wish there were a way Treedix were able to replace my Arduino, because I was following their photo for how to plug it in.

So it's just in parts, huge shocker there wish I'd have read the page, everything is scummy like this now...So what about the jumping the soldered pins in, it shows this bs diagram w. red wire jumper from one to the other (row) but I certainly don't see any? I'm supposed to trail solder across 2mm ? and not hit other pins in the row? this is stupid as it gets..the height for the normal pinheader row is far different too, so if you smartly decide to flip it upside down on a flat surface so you can do this... yep the rows are a different height and the pins are only halfway through so your solder will go all the way through or else you manually have to juggle to hold the pin header in (perfectly or the device will never fit in it... )Safe to say, when it doesn't work out i'm going to be returning a soldered mess back to them

Well, get used to cutting up bits of wire to solder in on back board. I mean, how hard would it have been to put trace on at least those connections? I don't mind soldering a few components, but having to chop up 30 little bits of wire to cross over the screw-in plugs to the push in plugs is way tedious. If they had just done a short piece of trace on those it would save an hour of trying to carefully balance tiny bits of wire between two posts and solder both at same time, no small feat in itself and must be carefully repeated all down the side on both sides without a short....I got it done, but really as cheap as it would have been to just make the board with proper trace. I don't see complaining about having solder loose components, I expect that...but this is way excessive...
