Product details

Overview

SLWSTK6241A from Silicon Labs is a wireless development kit comprising two BRD4001A mainboards and two BRD4542B radio boards, each integrating the EZR32HG320F64R55G 434 MHz wireless MCU with 64 kB Flash, 8 kB RAM, and 10 dBm RF output power. It enables rapid prototyping of sub-GHz IoT sensor nodes and low-power wireless applications using Simplicity Studio.

For engineers reviewing the SLWSTK6241A datasheet, SLWSTK6241A pinout, SLWSTK6241A application, or SLWSTK6241A equivalent, this kit delivers integrated J-Link debugging, Advanced Energy Monitor (AEM) current profiling, Packet Trace Interface (PTI), Virtual COM port, Si7021 environmental sensing, and memory LCD display - all in a production-ready evaluation platform for EZR32HG-based designs.

Technical Context

The SLWSTK6241A combines a Wireless Starter Kit Mainboard (BRD4001A) and BRD4542B radio board to form a complete reference system for the EZR32HG320F64R55G MCU. The mainboard provides USB/Ethernet J-Link debugging, real-time AEM current/voltage monitoring, PTI packet analysis, and VCOM serial bridging - all accessible via standard interfaces including ARM Cortex Debug+ETM, Simplicity Connector, and Mini Simplicity Connector.

The BRD4542B radio board implements a matched 434 MHz RF front-end with SMA antenna connector, USB 2.0 Full Speed device-mode support, and breakout access to all EZR32HG I/O pins. Power selection (AEM/USB/BAT) enables accurate energy profiling, USB-powered operation, or coin-cell battery testing - critical for ultra-low-power wireless design validation.

FAQ

What is the SLWSTK6241A used for?

The SLWSTK6241A is a complete wireless development kit for the EZR32HG320F64R55G 434 MHz wireless MCU. It enables engineers to develop, debug, and validate low-power sub-GHz wireless applications - including sensor networks, smart metering, and building automation - using integrated tools like J-Link debugging, Advanced Energy Monitor, Packet Trace Interface, and Simplicity Studio software.

Does the SLWSTK6241A include a debugger?

Yes, the SLWSTK6241A includes an on-board SEGGER J-Link debugger on each BRD4001A mainboard. It supports USB and Ethernet host interfaces, provides Serial Wire Debug (SWD), Virtual COM port (VCOM), and Packet Trace Interface (PTI) for real-time RF packet analysis - eliminating the need for external debug hardware when evaluating the BRD4542B radio board or external targets.

Can the SLWSTK6241A be used to debug external hardware?

Yes, the SLWSTK6241A supports external target debugging via its Debug Connector (ARM Cortex 19-pin), Simplicity Connector, and Mini Simplicity Connector. When configured in "Debug OUT" mode, it functions as a full-featured debugger for third-party hardware - delivering SWD, PTI, VCOM, and AEM-monitored voltage rail (VAEM) to external devices without modifying the SLWSTK6241A's internal radio board.

What sensors and peripherals are built into the SLWSTK6241A?

The SLWSTK6241A integrates the Silicon Labs Si7021 relative humidity and temperature sensor, a 128×128 pixel reflective memory LCD, two user push buttons (PB0/PB1), two yellow LEDs (LED0/LED1), and a 20-pin expansion header with pre-routed SPI/UART/I²C signals. All peripherals are directly connected to the EZR32HG320F64R55G and accessible via breakout pads or headers for rapid prototyping.

Is the SLWSTK6241A still recommended for new designs?

No - the SLWSTK6241A is marked "Not Recommended for New Designs" per Silicon Labs UG191 Rev. 1.01. It remains fully functional and supported for legacy development and maintenance, but new projects should consider Silicon Labs' newer Wireless Gecko (EFR32MG/MG21) or Mighty Gecko (EFR32MG22) starter kits, which offer enhanced RF performance, lower power, and updated software toolchains.
