XB3-24Z8UM 概要

The Digi XB3-24Z8UM is a Digi XBee 3 PRO Zigbee 3.0 surface-mount RF transceiver module operating in the 2.4 GHz ISM band with a U.FL antenna connector (antenna not included) and MMT (Micro Mount) form factor. Built on the Silicon Labs EFR32MG SoC, it delivers up to 8 dBm (PRO) transmit power and supports the IEEE 802.15.4 / Zigbee 3.0 protocol stack at over-the-air RF data rates up to 250 kbps with serial interface rates up to 1 Mbps.

An RF module (radio-frequency module) is a small PCB sub-assembly that integrates a wireless transceiver IC, matching network, crystal, and antenna interface into a single, EMC-compliant package. RF modules sit in the wireless connectivity hierarchy below discrete transceivers and above raw silicon ICs, abstracting RF design complexity so that MCU-based host boards can add wireless capability with a simple UART/SPI/I2C interface. The XB3-24Z8UM belongs to the XBee 3 PRO family, which adds extended RF link budget (PRO = higher TX power, lower RX sensitivity threshold) for longer-range mesh deployments.

Key features of the XB3-24Z8UM include 8 dBm (PRO) TX power, 2.4 GHz worldwide ISM band operation, Zigbee 3.0 mesh networking support, and a wide -40C to +85C industrial operating temperature range. The module integrates a Silicon Labs EFR32MG SoC with on-board microcontroller, eliminating the need for an external host MCU in many edge-IoT designs. UART, SPI, and I2C host interfaces are exposed through the 34-pin MMT land pattern. The U.FL RF connector enables use of an external antenna selected for the deployment enclosure.

Typical applications include building automation nodes, smart lighting controllers, smart energy metering, digital health peripherals, industrial sensor mesh networks, and any IoT device requiring certified multi-vendor Zigbee 3.0 interoperability. The XBee 3 platform is supported by Digi's XCTU configuration tool and Digi Remote Manager cloud integration, simplifying provisioning and OTA firmware updates.

When designing with this module, note that antenna selection is critical - although the U.FL connector is present, RF performance depends entirely on the chosen external antenna, its placement, and ground plane clearance. Allow at least 5 mm of keep-out under the antenna feed trace, follow the MMT footprint exactly, and avoid placing the module near large metal planes that detune the antenna.

The 2.4 GHz band provides global regulatory acceptance (FCC, ETSI, IC, KCC) without region-specific variants.
What is the transmit power of the XB3-24Z8UM?
The XB3-24Z8UM delivers +8 dBm (approximately 6.3 mW) of transmit power in its PRO configuration. According to the Digi XBee 3 PRO datasheet, this gives extended link budget versus the standard XBee 3 (non-PRO) at +16 dBm; the PRO variant here trades some TX power for better receiver sensitivity and lower power consumption. Range in open air typically reaches 60-120 m line-of-sight with a proper U.FL antenna.
What is the difference between the XB3-24Z8UM and the XB3-24Z8RM?
The XB3-24Z8UM uses a U.FL antenna connector (external antenna required, not included) in the MMT surface-mount form factor, while the XB3-24Z8RM has an integrated RF pad antenna for onboard trace designs. Both share the same 34-pin MMT footprint, Silicon Labs EFR32MG SoC, 2.4 GHz Zigbee 3.0 protocol, and +8 dBm PRO TX power, making them pin-compatible drop-in alternatives - select UM when using an external antenna and RM when you need a self-contained onboard antenna.
What is the difference between XB3-24Z8UM and XB3-24Z8PT?
The XB3-24Z8UM is the surface-mount MMT version with a U.FL connector for an external antenna, while the XB3-24Z8PT is the through-hole PCB antenna version. Both run identical Zigbee 3.0 firmware on the same EFR32MG silicon and share identical electrical characteristics. Choose UM for compact SMT designs with a chosen antenna; choose PT for prototyping or through-hole assembly with the convenience of a built-in PCB antenna.
What is the difference between XB3-24Z8UM and XB3-24Z8CM?
The XB3-24Z8UM is the surface-mount MMT module with U.FL connector, while the XB3-24Z8CM is the classic through-hole XBee form factor with similar antenna choices. Both support Zigbee 3.0 and share the same EFR32MG SoC, but the CM form factor is significantly larger and uses 2 mm through-hole pins. Choose UM for compact SMT designs; choose CM for prototyping, socketed designs, or when using standard XBee sockets.

PRO variants command a premium over standard XBee 3 modules due to extended link budget and lower RX sensitivity. Volume pricing is typically negotiated directly with Digi for OEM quantities above 5000 units.
Is the XB3-24Z8UM in stock?
The XB3-24Z8UM availability varies by distributor. DigiKey and Mouser typically maintain inventory, but lead times can extend to 8-12 weeks during allocation periods for the broader XBee 3 family. According to a 2022 Digi support forum thread, XBee 3 modules (XB3-24Z8xx) have experienced shortages with distant restock dates - check with each distributor for current inventory before committing to a design.
Can the XB3-24Z8RM replace the XB3-24Z8UM?
Yes, the XB3-24Z8RM is a drop-in replacement for the XB3-24Z8UM on the same 34-pin MMT footprint with identical Zigbee 3.0 protocol, 2.4 GHz band, and Silicon Labs EFR32MG SoC. The only difference is the antenna interface: UM uses a U.FL connector for external antenna, RM uses an integrated RF pad antenna for onboard trace designs. Both share the same PRO RF performance ratings and identical pinout on the MMT land pattern.
What is the best cross-brand drop-in replacement for the XB3-24Z8UM?
There is no true cross-brand drop-in replacement for the XB3-24Z8UM because it is a complete certified module with integrated antenna interface and regulatory pre-approval. Cross-brand Zigbee 3.0 modules (e.g., Silicon Labs EFR32MG-based MGM12P/MGM13P modules, Texas Instruments CC2652-based modules) require different footprints, different firmware, and re-certification of the end product. The safest same-footprint alternative is the XB3-24Z8RM (integrated antenna) or XB3-24Z8CM (through-hole). For new designs, consider the XB3-24Z8UM-J variant if available with your distributor.

選定ガイド

Choose the XB3-24Z8UM when you need a surface-mount Zigbee 3.0 module with an external antenna chosen for the deployment enclosure. The U.FL connector supports optimized radiation in metal-rich industrial or sealed medical housings where an integrated onboard antenna would be detuned. Choose the XB3-24Z8RM instead when your enclosure allows a compact onboard antenna and you want to avoid the U.FL connector and external antenna BOM. Choose the XB3-24Z8PT when prototyping with through-hole assembly, or the XB3-24Z8CM when using standard XBee sockets. For Japan deployments, the -J suffix variants (XB3-24Z8UM-J, XB3-24Z8RM-J) provide Japan regulatory certification. All variants share the same Silicon Labs EFR32MG SoC, Zigbee 3.0 stack, and Digi XCTU/OTA tool support.

主な差別化要因

  • External U.FL antenna option for optimized radiation (vs XB3-24Z8RM)
  • Surface-mount MMT form factor (vs XB3-24Z8CM)
  • PRO RF performance for extended link budget (vs XB3-24Z8RM (same PRO level))

設計ノート

Follow the Digi XBee 3 RF Module Hardware Reference Manual (90001543) MMT land pattern exactly. Maintain at least 5 mm of keep-out under the U.FL antenna feed trace and avoid placing the module near large ground planes or metal structures that detune the antenna. The MMT castellation pads require proper solder paste stencil aperture design - consult the reference manual for recommended paste volumes.

Antenna selection is critical for the XB3-24Z8UM - the U.FL connector is present but the external antenna is NOT included with the module. Choose a 2.4 GHz antenna with 50 ohm impedance matched to your enclosure's plastic composition. Per the Digi forum thread on RM-CM-UM variants, unused internal antenna traces on the PCB do not significantly interfere, but improper antenna selection will severely degrade range and link budget.

Design the host 3.3 V rail to deliver at least 250 mA peak (TX bursts at +8 dBm draw approximately 120 mA plus host MCU margin). Place a 10 uF bulk capacitor and 0.1 uF decoupling capacitor within 5 mm of the module's VCC pin. Avoid sharing the XB3-24Z8UM's supply with noisy digital rails; route a dedicated LDO output if possible. Peak currents during CSMA backoff can cause voltage droop if the host rail is undersized.
