Micro-B breakout USB card has protection pads for a strong and long lasting connection.

The DMX shield is a add-on for Arduino . It's an easy way to use the Arduino as a DMX-Master device, just add the shield DMX to the upper part of the Arduino .

This package includes a Sensor of Level of Water and a Sensor of Humidity from Solo. If the plates have water covering the sensor components, an analog value will be available on the "SIG" connection. The Sensor of Level of Water can detect up to 4cm of water. This way, you can check if your aquarium, or your pet's water bowl, still has enough water. You can use the Sensor of Moisture of the Soil to check your plant's soil or growing environment, for example.

The BLE shield has the function of adapting low-power Bluetooth as a serial port , which are specifically designed for Arduino boards and compatible boards, simple to use, simply connect and a ready is ready to be used.
