Digi XBee3 PRO (Zigbee 3.0): specs and pinout

2.4 GHz XBee 3-PRO radio module in the through-hole form factor with an RPSMA antenna connector, with a UART and SPI interface.

Pinout

Pin names are from the maker's hardware reference manual for the XBee 3 through-hole module. The manual covers the XBee 3 and XBee 3-PRO family; the RP-SMA variant is a through-hole part. The module has through-hole pins and cannot be wired to a breadboard without a carrier or adapter board; none is sold here, so these ideas assume you already own one.

Build with it

Project ideas for the Digi XBee3 PRO (Zigbee 3.0). Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.

• Wireless room sensor: Needs two of this module: one on the ESP32 node and one on the receiving board (for example the Raspberry Pi in the third idea). The module needs 2.1 V to 3.6 V and 140 mA at its top 19 dBm output, so it gets its own 3.3 V buck module fed from a 5 V USB supply rather than the ESP32 board's pin. UART pins are 3.3 V logic, matching the ESP32. The module has through-hole pins, so it also needs a carrier or adapter board that you already own (not sold here). Learning project.
• Indoor link tester: Each module runs from a 3.3 V buck module that can deliver more than the 140 mA transmit current. The ESP32's 3.3 V UART pins connect directly to DOUT and DIN. Short indoor range test. Learning project. Needs two modules, each on a carrier or adapter board that you already own (not sold here).
• Zigbee data receiver on a Pi: The Pi's UART is 3.3 V logic, inside the module's 2.1 V to 3.6 V range. The module takes 140 mA at 19 dBm, so it gets its own 3.3 V buck module with a shared ground. The module has through-hole pins, so it needs a carrier or adapter board that you already own (not sold here). Learning project.

Common mistakes

• Feeding it from a source that cannot give the transmit current. The maker lists 140 mA at 19 dBm on a 2.1 V to 3.6 V supply, so use a 3.3 V supply that can give more than that (source: link, p.26).
• Using 5 V signals or supply. The module supply is 2.1 V to 3.6 V, and input pins go up to VCC + 0.3 V (source: link, Electrical characteristics p.25).
• Hot-plugging. The manual says never to insert or remove the XBee 3 module while power is on (source: link, Attach the XBee 3 RF Module section).

Not covered by the official source

• The Zigbee user guide (firmware commands, network setup) was not read, so no Zigbee settings are listed.
• No carrier or adapter board for the module's through-hole pins is sold here; the ideas say you must already own one.
• The hardware manual covers the whole XBee 3 family; this page uses the XBee 3-PRO columns and the through-hole pin table.
