“This is a great little board. It is only slightly larger than the Arduino nano, but the build-in buzzer, switch and LEDs, make it an ideal development board. At less than half the price of the Arduino Nano it's also a bargain. I liked it so much I bought two.”
“Great for small microcontroller projects that don't require a lot of IO. Arduino nano compatibility makes it simple to program and its built in LEDS make debugging easier.”
