Examples include: LoRaWan, Cellular, Bluetooth, Power-over-Ethernet (PoE), 900MHz long range mesh, 2.4GHz dense mesh, wirelessHART implemented on 802.15.4 modules, WiFi, Ethernet 10/100, point-to-point, PTMP, USB-Serial…
Summary of available communications options:
| XBee RF(1) | USB/Serial(2) | Ethernet(3) | PoE(4) | |
| 100A1 | Yes | Yes | Yes | Yes, isolated |
| 0102G | Yes | Yes | Yes | Yes, non-isolated |
| 0102GXN | Yes | Yes | Yes | Yes, non-isolated |
Notes:
(1) XBee socket allows for any-XBee footprint and pinout compatible module, including but not limited to: Cellular, Bluetooth, WiFi, 802.15.4 in 900MHz or 2.4GHz, ZigBee, LoRa, Proprietary (DigiMesh) and similar devices and protocols. At a minimum, for low power applications, look for modules with low power sleep modes, and an output pin that either indicates wake/!sleep state or a GPIO pin in the XBee standard D1 position.
(2) For immediate use, connect a USB-Serial (3.3TTL) converter, ideally including one or more GPIO signals for power control, much like the readily-available FTDI off-the-shelf (OTS) cables. Supported speeds at the current typical firmware revisions are up to the range of about 1Mbps. Direct USB provisions are provided on the boards themselves and require firmware development to accommodate.
(3) Ethernet (and WiFi) is implemented via Digi Connect-ME module or Connect-WiMe and their variants.
(4) Power-over-Ethernet: All units capable using a Digi Connect-ME. Only the 0100A1 includes an option for true isolated PoE conversion from -48VDC to board level power. However, PoE can be provided at any voltage level and for R&D purposes the G/GXN boards breakout the PoE pins and thus allow board power via these pins.
