Jason A. ★★★★★

I needed a replacement for a fried Arduino Uno and this chip had the bootloader already installed, which saved me a ton of reprogramming hassle. The pinout matched my board perfectly.

Nicholas J. ★★★★★

Worked flawlessly as a drop-in replacement for the main controller in my weather station project. The pre-loaded bootloader saved me from having to mess with a programmer.

Riley Y. ★★★★★

Swapped out a fried chip on a custom board and it fired up on the first try with the pre-loaded bootloader, so no extra flashing hassle. Pinout matches the Uno perfectly, which saved me from rewriting any of my code.
