The Bluno Beetle Shield expands the Beetle's single analog and digital I/O pins to the 3 pin "gravity" interface, giving more power and ground connections and making it easier to attach gravity interface modules. It also includes a convenient external power supply and a 5-8v switch to power the board on and off. To use the shield, the Bluno Beetle is stacked on to the shield's I/O pins and then soldered in place.

This is a Micro SD(TF) module from DFRobot. It is compatible with TF SD card (commonly used in Mobile Phone) which is the most tiny card in the market. SD module has various applications such as data logger, audio, video, graphics. This module will greatly expand the capbility an Arduino can do with their poor limited memory.

This module has SPI interface and 5V power supply which is compatible with Arduino UNO/Mega. The Pinout is fully compatiblw with DFRobot's IO Expansion Shield V7.

This is an Arduino RF shield that works under 315Mhz. 315M hz is widely applied in areas like vehicle monitoring, remote control, home security system, wireless meter reading, guard monitor system, industrial data acquisition system, wireless tag, identification, non-contact RF card, small wireless data terminals, fire safety systems, wireless remote control system, biological signal acquisition, hydrological/meteorological monitoring, robot control and so on.

This RF Shield is compatible with our remote wireless keynob.

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
