Review: Great device, highly recommended - Very good! I'm coming from an Arduino Leonardo. This board is SIGNIFICANTLY faster, has a ton of very well designed libraries, and has zero hiccups during processing. I'm currently using it as a custom mouse/keyboard/joystick device I built as the brain. The serial port is insanely fast, have never seen it take over 1ms. It has everything built in you can think of. USB host? Yup. Ethernet? Yup. The only downside I can think of is the power consumption, and the heat. I put a heatsink on top of the chip just in case it was downclocking. You do need a little bit of soldering experience if you plan on using all the futures, but it's nothing difficult.
Review: incredibly powerfully and fast board - New to teensy , but can hardly wait to take advantage of speed, power and versatility . I have lots of projects planed

### ⭐⭐⭐⭐⭐ Good Board
*by C***Y on August 8, 2025*

Good little development board for Arduino type things. This one has a lot of I/O that was needed for this project. At 600MHz, this device is a lot faster than the Rabbit 3100 series it will be replacing. Can use the Arduino development tools to build software. Lots of support with many libraries to do just about anything you'll need to do. We'll see how it works in a production environment in the next months.
