The DFRobot Arduino-Compatible Screw Shield is a terminal expansion board that allows you to screw in jumper wires to a screw terminal for a much stronger and secure connection for your I/O and power pins. Feel secure with this arduino-compatible screw shield.

We commonly use:Green for digital I/O;Blue for Analog I/O;Red for Voltage

The Arduino XBee shield is designed to meet wireless sensor networks such as wifi, bluetooth 2.0/4.0 and zigbee. The module is easy to use, low power consumption, and the provision of critical data between devices reliable transmission.

μHex is the first low-power controller which is compatible with Arduino. It is very suitable for the battery power supply environment. A 210mAh CR2032 cell battery could make it work 60 days long.

• Bootloader is write protected, please do not attempt to update Bootloader.
• For large load applications (such as motor controlling), please connect VCC & GND directly or supply with independent power.

Add bluetooth 4.0 to your PC, Mac directly with this USB BLE-Link. It uses the USB package which is compact and compatible with v2.1 and earlier, and also supports the latest v4.0/Bluetooth Low Energy. Now you could use this adapter to receive/transmit data.

With two USB-BLE Link users can do point-to-point wireless transparent transmission, master-slave machine setting, and wireless programming. It can also work as a PC BLE wireless programming adapter. Comaptible all DFRobot BLE series modules: i.e. Bluno, Romeo BLE, etc

Beetle is a extremely small Arduino leonardo board. It derives its core notion from minimalism without compromising functionality.

As the smallest version of Arduino Leonardo, it enjoys similar powerful functionalities. Beetle aims to solve problems of low-cost controller, ease-of-using properly, and to provide a low cost solution for disposable projects, such as DIY projects, workshops, gift projects, E-Textiles and educational. For students and makers who can not afford too much on hardware purchasing, Beetle can be a great solution for them.
