Is this the same as a normal leonardo, or does the "development" in the name imply some other functionality?

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

Is there a program to be installed?

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).
