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

Product Description
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. |
Technical Specification:

- Analog Input Pins: 12
- DC Current per I/O Pin: 40mA
- DC Current for 3.3V Pin: 50mA
- Flash Memory: 32KB (ATmega32u4) of which 4KB used by boot loader
- SRAM: 2.5 KB (ATmega32u4);
- EEPROM: 1 KB (ATmega32u4);
- Clock Speed: 16MHz
- LED_BUILTIN: D13
- Digital I/O pins: D0-D13 and A0-A5 (D18-D23); the ICSP pins can be used as digital pins.
- Analog Inputs: A0-A5, A6-A11, that is, D4 (A6)、D6 (A7)、D8 (A8)、D9 (A9)、D10 (A10) and D12 (A11)
- PWM pins: D3, D5, D6, D9, D10, D11 and D13.

- Serial communication: D0 (RX) and D1 (TX)
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.

Hab die ganze Aktion mit 3 anderen Modellen verschiedenster Hersteller ausprobiert (Uno, Mikro und ein kleiner Leonardo -> alle NoName ) und bei keinem funktionierten mehr als 2 Fans.
Mit dem hier funktioniert das Ganze an den Pins 9, 10 & 11.
