Teensy LC (with Pins)

After receiving the right board, it's working flawlessly in my PinSim controller.

These units are so much fun! This is the first one that I ordered with pins already soldered to it, and that makes it even better. I use these to program lighting effects for models that I build, but these things are loaded with functionality that I haven't even used yet. You don't have to be a programming genius to figure it out unless you're doing something extremely complicated. Easy, fun, and it works great on USB power.

Used this as a timer to build a time delay circuit for arcade boot up

No problems and dropped right into place (as low-cost replacement for Teensy4.0 when not needing the features of the 4.0 (pinouts...)

Used it for a button box for a flight simulator. Fun to work with. Works great, super small, great value!

Drop into a breadboard and go. The Arduino IDE isn't always straightforward but thankfully more robust solutions exist that can utilize the command line tools.

I like the device for its power. However, having a Bluetooth and Wifi built in might be more usuful now days.Still powerful and well made platform for embedded work.

If you're a teensy fan, this is a great product. Lots of digital and analog pins, 32 bit processor, low price!
