RAK8211-NBS iTracker Module

iTracker RAK8211-NBS is a versatile developer board aimed at aiding in quick prototypes using NB-IoT. The board includes a vast array of connectivity options (NB-IoT, BLE 5.0 and GPS) and sensors. At the heart of the module is the venerable Nordic nRF52832 BLE processor. The NB-IoT connectivity is provided by the Quectel BC95 module. The iTracker module is Arduino friendly and can be programmed using the IDE.

The board also provides SWD interface for programming the nRF52832 core. The combination of BLE and NB-IoT provides flexible low power consumption development along with a myriad of application options ranging from telemetry to live tracking and environment sensing.

See how easy it is develop on the iTracker

14 Reasons why you should choose iTracker (RAK8211-NB0

  • 1. Multiple Radios
    • Support for BLE and GSM on one board for the best of short range and longe range communication use cases.
  • 2. Support for GPS
    • Can be used as a tracker along with internet connectivity using the onboard GSM module.
  • 3. Multiple on board sensors
    • IMU sensors enable fine grained orientation details to the developers to develop attachments for quadcopters and collision detection systems.
  • 4. Environmental sensors
    • BME 280 and the OPT 3001 enable measurement of atmospheric pressure (possibly altitude with some accuracy) and light values for environmental triggers and possible weather station.
  • 5. BLE provides low power use cases: with the presence of the nrf52 as the main processor handling the peripheral, we have a rich set of interrupt driven APIs and support for low power modes in software.
  • 6. Support for serial bootloader and DFU OTA bootloader
    • Makes software programming very easy for developers
    • Can use their android phones to send software updates OTA
  • 7. Support for various programming platforms
    • Arduino IDE
    • Nrf52 IoT SDK
    • Zephyr
    • RiotOS
    • Blynk APIs
    • Espruino JS APIs
    • Contiki OS
  • 8. Support for Mbed and pre built libraries for accessing the on-board sensors.
  • 9. Small form factor and slim profile makes it easy to integrate the board into existing designs easily.
  • 10. Extra GPIO exposed via HOST board provides the ability to add more peripherals to the board.
  • 11. HOST board provides serial to UART connector enabling the use of serial bootloader for programming
  • 12. 4G LTE and NB IoT variants provide the ability for developers to design products which can leverage the speed of 4G or the light weight NB IoT framework to send and receive data.
  • 13. Support for solar panels provides good outdoor usage using just solar energy. coupled with low power mode/sleep mode we can extend the working hours of the module from days to months.
  • 14. Support for battery and associated circuit provides flexible standalone operation
