DFRobot Bluno Mega2560 Microcontroller Board with Bluetooth 4.0
DFRobot Bluno Mega2560 Arduino-compatible microcontroller board with Bluetooth 4.0 BLE, 54 digital I/O ports and 16 analogue inputs.
The DFRobot Bluno Mega2560 Microcontroller Board is an Arduino-compatible board with integrated Bluetooth 4.0 (BLE) wireless communication and a 70 m transmission distance in free space.
Overview
Built around the ATmega2560 chip, the Bluno Mega2560 provides extensive connectivity for complex DIY projects, including robotics and home automation systems. Its wide operating voltage range and significant memory make it suitable for advanced makers and educators.
Power and Connectivity
The improved power supply accepts a broad input range of 5-23 V DC, allowing use with batteries, USB and universal adapters. The board provides 54 digital I/O ports, 14 of which offer PWM capability, along with 16 analogue inputs and 4 hardware serial ports (UARTs) for sensors, motors and other peripherals.
Wireless Capabilities
The integrated Bluetooth 4.0 module supports remote wireless updating of Arduino sketches, transparent serial communication and Bluetooth HID (Human Interface Device) functionality. It also supports iBeacon technology and can be debugged via AT commands.
