I was recently shown an Arduino-compatible board made by Cytron in Penang, Malaysia called the Maker UNO. I gather it began life as a very successful kickstarter that aimed to produce a better board and associated teaching materials for K-12 education.
It packs some nice additional features in the Uno form-factor:
- LEDs on all digital pins
- a piezo buzzer on pin 8
- a push-button on pin 2
Aside from looking pretty spiffy, a really nice feature is the price - currently listing for RM15 (~$3.60 USD)!
Here’s a quick demo sketch that exercises the LEDs, buzzer and push-button:
