Product details

Overview

XG28-RB4400C from Silicon Labs is a dual-band radio evaluation board built around the EFR32ZG28B312F1024IM68 Wireless Gecko SoC, delivering +14 dBm output power in the 868–915 MHz band and +10 dBm in the 2.4 GHz band. It integrates an SMA antenna connector for sub-GHz operation, an inverted-F PCB antenna and optional UFL connector for 2.4 GHz, and 8 Mbit serial flash for OTA firmware updates - enabling rapid prototyping of LPWAN and IoT edge nodes.

For engineers reviewing the XG28-RB4400C datasheet, XG28-RB4400C pinout, XG28-RB4400C application, or XG28-RB4400C equivalent, this board serves as a production-ready reference platform for evaluating EFR32ZG28 RF performance, validating antenna matching networks, and developing certified wireless stacks (e.g., Matter over Thread, Zigbee, or proprietary 868/915 MHz protocols) with full debug visibility via J-Link, PTI, and AEM.

Technical Context

The XG28-RB4400C implements a complete hardware reference design for the EFR32ZG28 SoC, including matched front-end networks optimized for 14 dBm at 868–915 MHz and 10 dBm at 2.4 GHz. It routes all critical RF paths with controlled impedance and integrates discrete baluns and matching components per band.

It interfaces exclusively with Silicon Labs Wireless Starter Kit (BRD4001A) or Wireless Pro Kit (BRD4002A) mainboards via standardized 2×25-pin plug-in connectors, enabling access to on-board J-Link debugging, Advanced Energy Monitor (AEM), Packet Trace Interface (PTI), and Virtual COM Port - all synchronized for time-correlated RF, power, and protocol analysis.

FAQ

What is the primary function of the XG28-RB4400C?

The XG28-RB4400C is a radio evaluation board that provides a complete, production-ready hardware reference for the EFR32ZG28 Wireless Gecko SoC. It enables engineers to validate RF performance, develop firmware, and test wireless protocols across both 868–915 MHz and 2.4 GHz bands - with integrated debug, power monitoring, and antenna interfaces. The XG28-RB4400C is not a standalone product but requires pairing with a compatible Silicon Labs mainboard (BRD4001A or BRD4002A).

Does the XG28-RB4400C include an on-board debugger?

No, the XG28-RB4400C itself does not contain an on-board debugger. Debug functionality is provided by the host mainboard - either the Wireless Starter Kit Mainboard (BRD4001A) or Wireless Pro Kit Mainboard (BRD4002A) - which integrates a SEGGER J-Link debugger, Packet Trace Interface (PTI), and Advanced Energy Monitor (AEM). The XG28-RB4400C connects directly to these resources via its plug-in interface.

What antenna options are supported on the XG28-RB4400C?

The XG28-RB4400C supports two distinct antenna configurations: an SMA connector for external antennas in the 868–915 MHz band, and an integrated inverted-F PCB antenna plus an optional UFL connector for the 2.4 GHz band. The kit ships with two dipole antennas (868 MHz and 915 MHz models) for immediate sub-GHz evaluation.

Can the XG28-RB4400C be used for regulatory testing?

Yes - the XG28-RB4400C implements the exact RF front-end design, matching networks, and layout guidelines specified in the EFR32ZG28 reference design documentation. Its calibrated output power (+14 dBm @ 868–915 MHz, +10 dBm @ 2.4 GHz), conducted emission characteristics, and antenna interface compliance make it suitable for pre-compliance and final certification testing (e.g., FCC, CE, RED) when used with approved antennas and test configurations.

Is the XG28-RB4400C compatible with Simplicity Studio?

Yes, the XG28-RB4400C is fully supported in Simplicity Studio v5 and later. It enables direct flashing, real-time energy profiling via AEM, packet-level RF analysis via Network Analyzer, and protocol stack configuration for Zigbee, Thread, Bluetooth LE, and proprietary PHYs. Simplicity Studio recognizes the XG28-RB4400C automatically when paired with a supported mainboard and detects the EFR32ZG28 SoC for seamless toolchain integration.
