## Description

Ideal for complex projects and prototyping, this Arduino-compatible board uses the ATmega2560 and CH340 USB interface, offers 54 digital pins with 14 PWM and 16 analog inputs, runs at 5V with a 16 MHz clock, has 256 KB Flash memory and stable connection for rapid development. Limited to 4 pieces per order.
The Arduino-compatible development board with ATMega2560 R3 microcontroller is a versatile solution for complex electronic projects, automation, robotics, monitoring systems, and educational applications.
Equipped with the ATmega2560 microcontroller, CH340 driver, and USB Type-C connector, this board offers modern connectivity and practical use for both programming and power supply.
It features 54 digital pins, of which 14 can be used as PWM outputs, as well as 16 analog pins, making it suitable for projects that require simultaneous connection of multiple sensors, modules, and peripherals.
It operates at 5V, has a 16 MHz frequency, and offers generous memory of 256 KB Flash, 8 KB SRAM, and 4 KB EEPROM, allowing the running of larger and more complex programs compared to simpler development boards.
The recommended power supply between 7V and 12V ensures stable operation in most common applications.
The board may be incompatible with the latest version of the CH340 driver from 2023; therefore, it is recommended to install the driver available in the Download section for correct operation and stable system recognition.
