Digi Introduces XBeeX3 IoT Modules with New Micro Form Factor, RF and Cellular IoT Connectivity

Digi International has just announced the Digi XBee3 series of RF modules and cellular IoT modules. The modules will be available in the existing Digi XBee SMT amd through-hole form factor, as well as a new micro form factor (19×13 mm) that’s about a third of the size of the original XBee RF module.

The RF modules will first come with ZigBee 3.0 and IEEE 802.15 support, but Bluetooth LE will be available through a firmware update later on, and WiFi and DigiMesh version will be brought to markets too. The first cellular module supports LTE Cat.1, but the company will eventually launch NB-IoT and eMTC (LTE Cat M) versions for Europe and the US respectively.

Some of the shared key capabilities listed by the company:

  • Over-the-air (OTA) changes to devices in the field for bug fixes and new features
  • Dynamically reconfigurable, based upon situation
  • Establish business rules to aggregate, store, transform and filter data via MicroPython programming capability
  • Create alerts and alarms for priority data and device health
  • Built-in support for advanced I/O including I2C, SPI, to drive modern sensors and actuators
  • Provide control logic for devices that require a microcontroller, without electronics redesign
  • With Digi Remote Manager, enables better bandwidth management via prioritization/ transmission of actionable information
  • Dynamic changes to behavior as requested from cloud platforms such as AWS and Azure (e.g., enabling real-time decisions based on local conditions)
  • Continue to operate during communications outages by dynamically executed logic that is not cloud-dependent

There are three RF models operating at 2.4 GHz up to 250 kbps, and available in the three package mentioned in the introduction (micro, surface mount, and though-hole):

  • Digi XBee3 ZigBee 3.0 supporting Zigbee Pro protocol
  • Digi XBee3 DigiMesh
  • Digi XBee3 802.15.4

Those modules, and corresponding development kits are certified for the US, Canada, and Europe.

More information is available about the modules and development kit on XBee product page. However, you won’t easily find any pricing information on their website,  so instead I had to do a web search about the part numbers to find out XB3-24Z8CM-J micro Xbee Zigbee 3.0 module is sold for $14.70, the XBee3 Zigbee Mesh development kit (XK3-Z8S-WZM) for $99, Digi XBee3 Cellular Smart Modem, LTE CAT 1 (XB3-C-A1-UT-001) for $99 as well, and the corresponding AT&T development kit (XK3-C-A1-UT-U) for $199.
