Best choice for a controller
By far the best controller to date. Highly recommended.

Awesomely powerful Arduino compatible development board 🤗
I love the Teensy 4.x and have purchased several for all of my maker projects.

The beast of microcontrollers
This thing is a beast, 600 mhz tons of pins, 7 serial ports, ethernet and USB host connectors among many other things... The only downside is you have to learn to solder....

If you need an Arduino that runs at Warp 11....
Mega LED panel people.... just be sure to buy the appropriate Ada / Etc shield.

Misleading listing (just a little)
Awesome product, the Amazon listing is just a little misleading. PJRC has many Amazon listings for Teensy products, and a lot specify “(Without Pins)” somewhere in the listing to make sure you are aware the Teensy board does not come with pre-soldered pins. This listing does not include the Without Pins disclaimer, so I assumed it comes with pins… it does not. :(

No LEDs in Ethernet connectors?
Ethernet LEDs don't light.
