Description:

The Keyestudio UNO R3 is an advanced development board designed to provide a robust platform for your projects. It features the ATmega328 microcontroller, offering excellent processing capabilities. With 32KB of Flash memory, 2KB of SRAM, and 1KB EEPROM, the board is well-suited for complex projects. It has 14 digital I/O pins (6 with PWM), 6 analog input pins, and operates at 16 MHz. The board includes additional I2C pins, IOREF, and a voltage switch (5V/3.3V), making it compatible with a wider range of components. The ATmega16U2 chip improves USB communication. It is compatible with the Arduino IDE and is ideal for makers and educators.

Principle of Work:

The Uno board is based on Free Hardware and Free Software concepts. It works with the Arduino IDE to write and upload sketches. An onboard Serial Converter and bootloader make programming easy. The board includes memory types: Flash (32KB), SRAM (2KB), and EEPROM (1KB). It runs at 16 MHz and supports USB or external power. Digital and analog I/O pins enable sensor and module interfacing. A USB-to-serial chip facilitates communication, while a bootloader enables uploads without an external programmer. Libraries simplify usage of sensors/modules, and the Arduino IDE provides tools for writing and uploading code.
