🔌 Teensy 4.1 Board (No Pins) Review

The power this thing has is mind-blowing compared to Arduinos. In terms of computing power, it's roughly the same as the Raspberry Pi, but doesn't run an operating system. This means you can use Teensy for real-time applications without occasional interruptions from the operating system. The downside to this is that you cannot run Linux applications on Teensy. If you want to run Linux, Pi is a better fit. This device is not for the faint of heart. Documentation is poor and scattered everywhere,

I haven't had much luck with this board. I thought I'd branch out and try something new. It didn't go so well and I went back to what I know, esp32, Adafruit boards like QT py or Pico etc. It's all pretty easy to get started in either Arduino IDE or Circuitpython.

This is my first time using Teensy - and I'm very impressed with the speed. My application was an embedded 320x240 LCD control over SPI and I needed a high refresh rate. I was able to update a full color image on screen in about 50ms without any optimization. This device can be programmed quickly and easily once you are familiar with the Arduino IDE (be sure to follow the installation instructions carefully as only specific versions of the IDE are supported). Great value for money and offers a…

Loaded with Raspberry Pi power with limited Arduino control. If you want maximum control over your contacts, timing, clock cycles, reliable storage, battery and more, this is the board for you. It also has an inexpensive $8 ethernet port, so for $40 you get one of the highest performing 32-bit Arduino compatible boards that has a fixed ethernet connection, an SD card, and a real-time clock with little up to no effort supported. The only downside is that there is no easy remote firmware upgrade…

I needed a fast Arduino compatible processor for an iterative solver involving matrix manipulation and complex numbers. Arduino Mega completed the program in 169 seconds. Seeeduino XIAO (M0, 32bit, 48MHz) took 89 seconds. Teensy 3.5 (M4, 32-bit, 120MHz) took 14 seconds. I thought it was pretty good until Teensy 4.1 (M7, 32bit, 600MHz) finished it in 0.45 seconds! But it seems a little touchy; I had to use a very short USB cable to communicate serially with the serial monitor. If you're looking…
