KEYESTUDIO Leonardo R3 Microcontroller Development Board with USB Cable Kit for Arduino Project
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.
SunFounder R3 BoardBundled with Mega 2560 R3 ATmega2560-16AU Board for Arduin
R3 board compatible with Arduino. The board for Arduino use ATMEGA16U2 chip, Faster transfer rates and more memory..
R3 board control using r3 ATmega328P chip. Includes new pin configuration (SCL, SDA, IOREF).Clearly print on the female header connector, more precise and easier to use the wire..
The mega 2560 R3 Board is 100% compatible with Arduino. Powered via the USB connection or with an external power supply. The power source is selected automatically..
The ATmega2560-16au has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library). Comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files)..
This version is optimized in the original version, both to ensure consistent and compatible with the original, but also easy to use..
