Teensy 4.1 (with Pins)

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. Below is set for 816MHz.Example:; PlatformIO Project Configuration File;; Build options: build flags, source filter; Upload options: custom upload port, speed and extra flags; Library options: dependencies, extra library storages; Advanced options: extra scripting;; Please visit documentation for the other options and examples; https://docs.platformio.org/page/projectconf.html[env:teensy41]platform = [email protected] = teensy41framework = arduino;build_flags = -O3 ; <--- compile for fastest performance;build_flags = -DF_CPU=720000000 -O3 # For 720MHz ; <--- needs coolingbuild_flags = -DF_CPU=816000000 -O3 ; ;# For 816MHz ; <--- needs solid cooling;build_flags = -DF_CPU=1000000000 -O3 ; <--- needs lots of cooling; upload_protocol = teensy-guilib_deps =adafruit/Adafruit BusIOAdafruit [email protected]@1.0ftrias/TeensyThreads@^1.0.2sparkfun/SparkFun Qwiic GPIO TCA9534 Arduino Library@^1.0.0cytrontechnologies/Cytron Motor Drivers Library@^1.0.1adafruit/Adafruit Unified Sensor@^1.1.14

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.

Exactly as it describes.

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.

I'm hearing great things about this! (Preposted)

It started smoking when I plugged it into my computer.

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.
