| Features | Bluno is first of its kind in integrating Bluetooth 4.0 (BLE) module into Arduino Uno. Compatible with all Arduino Uno pins, work well with any UNO-based expansion board. |
Bluno Romeo is a BLE main controller designed for robot lovers. It integrates motor driver, communication interface of all sorts, IO expansion ports, etc.
Suitable for Arduino robot fans.
|
Bluno Mega is an Arduino controller with 54 digital ports, 16 analog ports, 4 UARTs and plenty of IO ports.
Applicable to large projects that requires many sensors.
|
Mega1280 has as many IO ports as Mega2560, but comes with a smaller Flash. Besides, its price is lower than Mega2560.
Suitable for low-cost projects requiring many sensors.
|
Bluno nano is BLE main controller, small as a gum, compatible with small breadboards.
Perfect for BLE projects with limited space or weight.
|
39 GPIO can be configured as interrupt control; up to 5 serial communication interfaces. | Bluno M0 is the only arduino controller that supports 5V standard logic level. It adopts arm Cortex-M0 core and carries IIS interface. |
