The Sparkfun Redboard

This is not the Arduino work-alike if you're not looking for the wifi, the bluetooth, the BLE, or the super-blinky. It's just a solid version of the gold-standard Arduino R3 Uno by Sparkfun. Ideal for applications where you don't want all the other feature-sets to mess up your application where you just need an Arduino Uno R3 reference design. And since Sparkfun engineered and build it in the USA, you know it's a faithful work-alike.

This key features of this version of the Redboard features mini-USB, a SMD Atmega328 IC, and the rock-solid FTDI FT231X USB interface IC.
