Make sure to check product before throwing packaging away in case it doesn’t turn on.
I’m only giving this 4 stars because the first one I was sent was defective and just didn’t work. BUT they promptly went over a new one and it’s great, exactly what I was looking for!

Beware: Received Used and Damaged Product from SparkFun
I bought a new Teensy 4.1 board, which was supposed to be new and sold by SparkFun on Amazon. When I received it, I was very disappointed to find that the board had already been used. Wires were soldered and then cut on several pins, and there were clear signs of use, which indicates this was not a new product.After removing the wires, I tried to make it work with a simple LED blink program. The board started to get hot, and nothing lit up, not even the power-on LED. The board seems to be defective.I paid for a new item and received a used, potentially damaged one. This is not the level of quality and service I expect from SparkFun. I am extremely disappointed with this experience. Buy with caution.
