บอร์ด Leonardo R3 development board ATMEGA32U4, blue board with data cable (Arduino-compatible board) พร้อมสายไฟ

This is a clone of the lasest version of original Leonardo (arduino-compatible board). There is a usb cable inside the package for seperator computer connection. We always recommend to use original products. Product content: Leonardo R3 (arduino-compatible board) A to B Usb cable Leonardo (arduino-compatible board) is an Atmega32u4 based microcontroller board. There are 20 digital I/O pins (7 of them can be used as PWM out, 12 of them can be used as analog input), 16 MHz crystal oscilator, micro usb socket, power socket, ICSP connector and a reset button on the board. There are everything for the microcontroller to work on the board. The board can be easily connected to a computer via usb, can be supplied with an adapter or a battery. Leonardo board is seperated from other arduino-compatible boards by using ATmega32u4 microcontroller, Atmega32u4 is able to communicate with a computer directly thus it does not need an USB - Serial converter. Thanks to these features, Leonardo can be introduced to computer as not only virtual COM port but also as peripherals such as console and mouse too.
