Bluno Mega2560 Microcontroller Board with Bluetooth 4.0

The Bluno Mega2560 is a powerful, Arduino-compatible microcontroller board that seamlessly integrates Bluetooth 4.0 (BLE) wireless communication. Building upon the robust ATmega2560 chip, it provides extensive connectivity for complex DIY projects, from robotics to home automation systems. Its enhanced feature set includes a wide operating voltage range and significant memory, making it a versatile choice for advanced makers and educators.

A key upgrade is the improved power supply system, which accepts a broad input range of 5-23V DC, offering greater flexibility for various power sources, including batteries, USB, and universal adapters. The board boasts 54 digital I/O ports (14 with PWM capability), 16 analogue inputs, and 4 hardware serial ports (UARTs), providing ample interfaces for sensors, motors, and other peripherals.

Wireless Capabilities

The integrated Bluetooth 4.0 module supports a remarkable 70-metre transmission distance in free space. It enables features like remote wireless updating of your Arduino sketches, transparent serial communication, and Bluetooth HID (Human Interface Device) functionality. It also supports iBeacon technology and can be debugged via AT commands, offering professional-grade wireless development tools.

Specifications & Programming

With a 16MHz crystal oscillator, 128KB of flash memory (4KB for bootloader), 8KB of SRAM, and 4KB of EEPROM, it handles large, complex code with ease. Programming is straightforward via the embedded USB bootloader, eliminating the need for external programmers. The board also supports USB updates for the BLE chip's firmware. Each digital I/O pin can source or sink up to 40mA, sufficient for driving LEDs and small modules directly.

Compact yet feature-rich, the Bluno Mega2560 is the ideal centrepiece for demanding electronic projects that require robust processing, extensive I/O, and reliable wireless communication,
