Review on 🔌 Teensy 4.1 Board (No Pins) by Chip Palmer

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 powerful alternative to the Raspberry PI with possibly the best hardware support when running without Linux installed.
