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...
