This HAT is the shield board that allows you to use XBee module with Raspberry Pi.
XBee is the wireless communication module developed by DIGI. With rely on Authentic Digi XBee Footprint, you can connect Digi Zigbee modules on top of this Raspberry Pi XBee Shield. Also, LTE Cat 1, LTE-M, NB-IoT, 3G, DigiMesh and Thread XBee modules are compatible with this Sixfab Raspberry Pi XBee shield. Easy communication over USB or Serial between Raspberry Pi and XBee is possible.
- Long Header: If you plan to attach another Raspberry Pi HAT or add-on board on top of the XBee Shield, you will definitely need this variation. Also, using GPIOs with jumper cables is possible with these male headers.
- Short Header: Are you going to use the XBee shield only, will not add another Raspberry Pi HAT or shield on top of it? Or you’ve already attached a board with a long header on Raspberry Pi and you’re planning to plug this shield on top? This header option is suitable for you.
- Without Header: If just the plugging XBee shield via micro USB cable to Raspberry Pi is enough for you, or you’ve already attached a bulky shield on Pi, doesn’t need directly UART communication, this slim, headerless shield works greatly. For knowing what you missing without headers, take a look at the Pinout Diagram of the shield, these pins will be unconnected.
- Fully compatible with Raspberry Pi models that have the 40-pin GPIO header (3, 2, B+, A+, Zero)
- With the authentic Digi XBee footprint, you can connect any Digi XBee module
- You can communicate with the XBee module directly via micro USB, thanks to FTDI USB to UART converter chip. It helps you to connect the Shield to PC via USB and configure the modules directly over XCTU application.
- RX-TX, Power ON/OFF, RSSI and User LEDs
- 1-Wire Sensors Interface
- RTS, CTS and RSSI pins connected to both Raspberry Pi’s GPIOs and FTDI USB-UART converter IC.
- The mounting holes fit the Raspberry Pi Zero exactly
- Optional headers as long, short and headerless
- POWER(PWR): When the shield is powered up, this RED led turns on
- USER (U.LED): The GREEN user led can be controlled by driving the 22nd GPIO.
- RSSI: The BLUE led. Received Signal Strength Indicator (RSSI) measures the amount of power present in a radio signal. It is an approximate value for signal strength received on an antenna. The RSSI is measured in dBm. A greater negative value (in dBm) indicates a weaker signal. Therefore, -50 dBm is better than -60 dBm. XBee module’s pin 6 can be configured as an RSSI pin that outputs a PWM (pulse-width modulation) signal representing this value. To do so, configure P0 pin of XBee as RSSI.
- USER (U.BUT): This push button connected to GPIO24 and pulled up HIGH state by default. When you push the button, you will read LOW state from GPIO24.
- RESET (RST): When the XBee is in powered on, it can be reset by pushing the RESET button for at certain time. Also, driving GPIO27 to the HIGH state will cause a reset.
