## 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20wireless%20room%20temperature%20and%20pressure%20node%20that%20sends%20readings%20from%20an%20ESP32%20through%20a%20Zigbee%20radio%20module%20to%20a%20second%20Zigbee%20module%20on%20the%20receiving%20side): 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20an%20indoor%20packet%20counter%20between%20two%20ESP32%20boards%20that%20talk%20through%20Zigbee%20radio%20modules%20and%20show%20counts%20on%20an%20OLED): 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20Zigbee%20data%20receiver%20on%20a%20Raspberry%20Pi%205%20that%20reads%20a%20radio%20module%20on%20the%20Pi%27s%20serial%20pins): 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](https://www.digi.com/resources/documentation/digidocs/pdfs/90001543.pdf), 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](https://www.digi.com/resources/documentation/digidocs/pdfs/90001543.pdf), Electrical characteristics p.25).
- Hot-plugging. The manual says never to insert or remove the XBee 3 module while power is on (source: [link](https://www.digi.com/resources/documentation/digidocs/pdfs/90001543.pdf), 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.
