The Teensy 2.0++ compatible USB AVR Development Board is a compact and powerful microcontroller platform based on the AT90USB1286 from Atmel (Microchip). Pre-loaded with a bootloader, the board allows you to upload code directly over a standard USB connection without requiring a separate programmer. This makes it an ideal choice for beginners, hobbyists, educators, and professionals working with AVR microcontroller development.
