About this item

  • 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.
  • The keyestudio Leonardo is a microcontroller board based on the ATmega32u4,It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.
  • The Leonardo differs from other controller boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor.
  • This allows the Leonardo to appear to a connected computer as a mouse and keyboard.
  • Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging

KEYESTUDIO Leonardo R3 Board

KEYESTUDIO Leonardo R3 is an ATmega32u4 microcontroller board.

The Leonardo differs from other Arduino boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor.

The Leonardo is a great because you can use it to emulate a keyboard/mouse/joystick, which is handy for many projects.

Power Supply:

The board has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

The keyestudio Leonardo can be powered via the micro USB connection, or via an external power supply jack (DC 7-12V) or even with female headers Vin /GND (DC 7-12V).

Memory Store:

The Atmega32u4 of KEYESTUDIO Leonardo R3 Board has 32KB of flash memory for storing code (of which 4 KB is used for the bootloader), 2.5KB of SRAM and 1KB of EEPROM (which can be read and written with the Eeprom library).

Board Model:

Neat little Leonardo r3 board works just like the original!

Another great Arduino alternative. It works fine and the quality is good. The yellow and black theme is unique.

Regarding how to use:

Select the Arduino Board

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.

Features This is quite possibly the best electronics STEM kit for kids to understand how things are assembled and how computers and robots work with programming. It is the equivalent of a R3 controller with a built in Wiznet 5500 ethernet module. Powerful Motor Driver Shield, Bluetooth 4.0 Supporting Android, iOS APP, light follow, obstacle avoidance modes,etc. This is a small and breadboard-friendly board based on the ATmega328. Comes with 4 x TT Motor 3-6V Uniaxial DC Gear Motor with 4X Robot Wheels for DIY Based on the Wiznet W5100 ethernet chip, this ethernet shield will allow Arduino Mega 2560/R3 to connect to the internet.

Works great!

Works great!
I've been impressed with KeyStudio products and their Leonardo is no exception. Works exactly as it supposed to. I used mine to make a custom controller for an arcade trackball and it did the trick nicely. (Note in the attached image I also used an expansion shield on the Leonardo so the actual KeyStudio Leonardo is pretty much hidden.)
