Product Description

Instruction ADUINO LEONARDO development board is our latest and easy-to-use open source controller. It has 23 digital input and output ports, 7 PWM ports and 12 analog input ports. Compared to other versions of Aduino, it uses a separated USB-Serial conversion chip, and only one chip Atmega32u4 to achieve USB communication and control. USB feature supported by original Atmega32u4 also allows Leonardo to simulate mice and keyboard. Specifications Controller: ATmega32u4 Operating Frequency: 16 MHz Operating Voltage: 5V Input Voltage (recommended): 7-12V Digital IO Ports: 23 PWM Ports: 7 Analog Input: 12 Maximum Current of 5V digital / analog port: 40 mA Maximum Current of 3.3V digital / analog port: 50 mA Flash Memory: 32 KB (ATmega32u4) of which 4 KB used by bootloader SRAM: 2.5 KB (ATmega32u4) EEPROM: 1 KB (ATmega32u4 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 D1 SPI: ICSP pin. SPI communication can be supported by using the SPI library. It should be noted that the SPI pin is not connected to any of UNO digital I / O pins, they can only work on the ICSP port. This means that if your expansion board does not have a 6-pin ICSP Pin, then it will not work. LED: 13. There is a built-in LED on the digital pin 13, when the pin is high level, LED is on and the pin is low level when the LED is off.
