Product details
Overview
SLWRB4306B from Silicon Labs is a Bluetooth 5.0 LE evaluation board for the BGM13P wireless module, enabling rapid prototyping of Bluetooth Mesh and long-range IoT applications. It integrates the BGM13P32F512GA-V2 module (19 dBm TX, integrated chip antenna), ARM Cortex-M4 core at 38.4 MHz, 512 kB flash/64 kB RAM, and hardware crypto accelerators. Designed for development of battery-powered industrial sensors and smart home gateways.
For engineers reviewing the SLWRB4306B datasheet, SLWRB4306B pinout, SLWRB4306B application, or SLWRB4306B equivalent, this page delivers verified hardware interface details, power configuration guidance, UART/USB debug connectivity, regulatory-compliant RF layout references, and firmware update workflows using Simplicity Studio.
Technical Context
The SLWRB4306B implements a complete reference design for the BGM13P module, featuring dual power supply paths (3.3 V USB and 1.8–3.8 V external), configurable antenna selection (chip antenna or U.FL), and direct connection to the onboard EFM32PG12B MCU for host control. It supports all BGM13P energy modes (EM0–EM4) with real-time current measurement via shunt resistors.
Hardware-level debugging is enabled through SWD and PTI interfaces, while the onboard CP2104 USB-to-UART bridge provides simultaneous NCP mode communication and bootloader access. The board includes dedicated test points for RF performance validation, including RX sensitivity (-94.8 dBm @ 1 Mbps) and TX spectral mask compliance per FCC/CE.

FAQ
What is the primary function of the SLWRB4306B evaluation board?
The SLWRB4306B evaluation board serves as a fully validated hardware platform for developing and testing applications based on the BGM13P Bluetooth 5.0 LE module. It provides immediate access to all module I/Os, integrated USB-to-UART bridging, SWD debugging, RF test points, and pre-certified antenna layout - enabling rapid firmware bring-up, protocol stack validation, and RF performance characterization without custom PCB design. SLWRB4306B is not a standalone product but a development enabler for SLWRB4306B-based end devices.
Does SLWRB4306B support both Bluetooth LE and Bluetooth Mesh protocols out of the box?
Yes, SLWRB4306B ships with the Gecko Bootloader 1.4.1 and Network Co-Processor (NCP) application from Bluetooth SDK 2.7.0.0, which natively supports Bluetooth 5.0 LE features including long range, high throughput, and advertising extensions required for Bluetooth Mesh provisioning and relay operation. Firmware updates to newer SDK versions retain full SLWRB4306B compatibility via Simplicity Studio.
Can SLWRB4306B be used for FCC/CE pre-compliance RF testing?
Yes, SLWRB4306B incorporates the same RF layout, matching network, and antenna structure validated in the BGM13P's official FCC ID: 2AOKB-BGM13P32 and CE/UKCA certification reports. Its SMA test port provides direct access to the RF path before the BALUN, allowing accurate measurement of conducted emissions, TX power, and RX sensitivity - making SLWRB4306B suitable for pre-compliance lab validation prior to final product certification.
How is power managed on the SLWRB4306B board when using the BGM13P module?
SLWRB4306B implements dual-path power regulation: USB 5 V powers the CP2104 bridge and generates 3.3 V for BGM13P DVDD/IOVDD via an efficient DC-DC converter; external 1.8–3.8 V input bypasses USB and feeds the same regulator. Current consumption across EM0–EM4 energy modes is monitored in real time using on-board shunt resistors and ADC channels, with values traceable to the BGM13P's published specs (e.g., 1.4 μA in EM2 Deep Sleep). This architecture ensures SLWRB4306B accurately reflects production power behavior.
Is the SLWRB4306B compatible with Simplicity Studio and third-party IDEs?
Yes, SLWRB4306B is fully supported by Simplicity Studio v5.x, providing one-click firmware flashing, real-time energy profiling, packet trace visualization, and Bluetooth Mesh network builder tools. It also supports GCC-based toolchains (e.g., SEGGER Embedded Studio) via standard SWD interface and OpenOCD configuration. All pin mappings, debug scripts, and SDK examples referenced in Silicon Labs' official documentation are validated for SLWRB4306B - no hardware adaptation is needed.
