## Description

KEYESTUDIO Leonardo R3 Development Board with USB Cable for Arduino

## Features

- Please NOTE: Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino. If you don't choose the correct development board type, it will cause the compilation to fail to transfer. So this is a place that needs special attention.KEYESTUDIO leonardo R3 is fully compatible with the official version, with the same circuit array
- It is our newest open-source controller, which has cool yellow-black design and twenty-three digital I/O ports, seven PWM ports and twelve analog input ports
- Maximum allowable current of 5V digital/analog port: 40 mA, and of 3.3V digital/analog port: 50 mA; Working voltage: 5V; Input voltage (recommended) : 7-12v
- Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging
- Main control chip is ATMEGA 32u4, adopting the United States ATMEL original. 【Tutorial download: 】https://fs.keyestudio.com/KS0248

## 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).
