Teensy 4.1 (with Pins)

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.

Trying it out for my robot. I need speed and lots of I/O. So far it programs like an Arduino, programs upload really fast, CPU itself seems very fast, and has multitasking with: #include <TeensyThreads.h>I'm very impressed.Check it out (Specifications):- 10/100 Mbit DP83825 PHY Ethernet- USB Host (5 Pins w/ Power Management)- Micro SD Socket SDIO (4 Bit Data)- 35 PWM Pins- 18 Analog Inputs- 8 Serial Ports- 8 Mbyte Flash Memory- QSPI Memory (2 Chips Plus Program Memory)- 42 Breadboard Friendly I/O- 7 Bottom SMT Pad Signals- 6 SD Card Signals- 55 Total IO PinsThe Teensy 4.1 is crazy fast, and you can overclock it easily with a compiler code to 1GHz.

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.

Es para un proyecto de la universidad de mi hijo, pero no hay dudas que está bien

I saw several comments that the board did not have the Pins soldered on, but it did. Have the Teensy breadboarded and checked all digital pins and all works great. Teensy 4.1 is an amazing device. Also, I received the order the next day after ordering.

It has more features than an arduino, packed into a smaller form factor. I was recommended this little device by Zack Freedman on youtube, and I must say, I haven't been disappointed.It requires a bit of extra software but is almost as easy to use as a standard atmega arduino, but is many times more powerful. If you don't need that, then it may be better to go for a cheaper option like an arduino nano, but this will last you through most any project.

Using this microcontroller for a CNC project and it's never run so smoothly.Can 1/16 microstep 4 axis simultaneously and had time to run some of my clunky code.Much faster then an Atmel 2650 Mega and way smaller.

The listing clearly says "with pins" but it did not come with any. Otherwise - great board! I had some spare headers and don't mind soldering them on myself but if you're not set up to solder on your own headers don't buy this listing.
