Leonardo R3 Microcontroller Development Board with USB Cable Kit for Arduino

Description: Leonardo R3 Microcontroller Development Board with USB Cable Kit for Arduino 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 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 Specification Controller: ATmega32u4 Working frequency: 16 MHz Working voltage: 5V Input voltage (recommended): 7-12v Digital I/O port: 23 PWM channel: 7 Analog input: 12 Maximum allowable current of 5V digital/analog port: 40 mA Maximum allowable current of 3.3V digital/analog port: 50 mA Flash Memory: 32 KB (ATmega32u4) of which 4 KB used by boot loader SRAM: 2.5 KB (ATmega32u4) EEPROM: 1 KB (ATmega32u4) Other related instructions Digital IO port: 23 (D0 - D13, D14-MISO, D15-SCK, D16-MOSI, D18-23 [A0-A5]) Analog input: 12 (A0 - A5, D4 - A6, D6 - A7, D8 - A8, D9 - A9, D10 - A10, D12-A11) Serial communication: D0 (RX) and D1 (TX) IIC communication: D2 (SDA) and D3 (SCL) External interrupt: D3 (interrupt 0), D2 (interrupt 1), D0 (interrupt 2), D1 (interrupt 3) and D7 (interrupt 4) PWM port: D3, D5, D6, D9, D10, D11 and D13 SPI: ICSP pins.Support SPI communication by using the SPI library. It is important to note that SPI pins do not connect to any number I/O pins like UNO, they can only work on the ICSP port.This means that if your expansion board has no ICSP pin connected to the 6 feet, it will not work. LED: 13. There is a built-in LED on the digital pin 13. When the pins are high level, LED is bright;when the pins are low level,the LED is not bright.
