ATmega328 UNO development board

Description

This board is a microcontroller board based on the ATmega32u4 (Arduino® Compatible leonardo). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

This product is a replacement of: VMA103

Features

• Full compatibility with Arduino Leonardo: The board is 100% compatible with Arduino Leonardo, allowing existing code and libraries to be used without any issues.
• Suitable for both beginners and advanced users: The ATmega32U4 Leonardo Development Board is easy to program with the Arduino IDE, while also being powerful enough for advanced HID and embedded applications.
• Good memory capacity: The development board features 32 kB flash memory (with 4 kB used by the bootloader), 2.5 kB SRAM, and 1 kB EEPROM for data storage.
• USB functionality without an extra chip: Thanks to the ATmega32U4 microcontroller, the board can communicate directly with a computer as a mouse, keyboard, joystick, or MIDI device, without requiring an additional USB-to-serial converter.
• Low power consumption: The module operates at 5V and can be powered via USB or an external power source (recommended 7-12V).
