Features

 Integrate with the Xbee socket

Available to be connected to Arduino or Raspberry Pi B+ directly either

Compatible with BLE Link(BT4.0)/Bluetooth Bee(BT2.1) and xbee modules

 Embeded DS1307 RTC module,which keeps time of the Pi even when the power is off, or the

battery removed

 Bidirectional logic converter for Raspberry Pi B+ GPIO to convert signal between 3.3v and 5v

 3 pin headers sensor port for Arduino pins and B+ GPIO, directly compatible with hundreds of

Arduino sensors and modules,like:

Relay Module V3.1 for IOT AC control

Analog pH Meter Kit for monitoring Water quality of your pool

SHT1x Humidity and Temperature Sensor

Motion Sensor for security and human detection

And so on...
