## Questions & Answers

**Q: is this leonardo HID compatible?**
A: Yes

**Q: Is this the same as a normal leonardo,  or does the "development" in the name imply some other functionality?**
A: I was looking for an UNO R3 (2016!) for a Grove sensor project.  It is a regular, normal UNO board.  I used  the Arduino IDE to program Seeed Studio's Grove watering, temperature sensors. I also purchased a similar board "MakerBest Hight Quality Compatible Arduino UNO R3 ATmega328P Development Kits " for Elenco's Snapno kit.  Both work fine and both for developing projects using UNO boards.  Hope this helps

**Q: will this device run micropython?**
A: sorry ,it can't

**Q: Is there a program to be installed?**
A: It's Ardunio-based, so you'll have to write the code and load it in. There are a lot of tutorials out on the web and pre-existing code that make it easy (or easier than starting from scratch).
