Product details
Overview
SLWSTK6021A from Silicon Labs is a complete EFR32xG22 Wireless Starter Kit comprising a BRD4002A Wireless Pro Kit Mainboard, BRD4182A 2.4 GHz 6 dBm radio board, BRD4183A QFN32 radio board, and debug cable - enabling rapid evaluation and development of Bluetooth LE, Zigbee, and Matter applications on the EFR32MG22 SoC with 512 kB Flash and 32 kB RAM.
For engineers reviewing the SLWSTK6021A datasheet, SLWSTK6021A pinout, SLWSTK6021A application, or SLWSTK6021A equivalent, this kit delivers integrated J-Link debugging, Advanced Energy Monitor (AEM), Packet Trace Interface (PTI), Virtual COM port, and hardware peripherals including Si7021 temperature/humidity sensor and 128×128 memory LCD - all optimized for low-power wireless prototyping.
Technical Context
The SLWSTK6021A integrates the EFR32MG22C224F512IM40 SoC - a 2.4 GHz sub-GHz capable wireless MCU supporting multiprotocol stacks (Zigbee, Thread, Bluetooth LE, Proprietary) with 6 dBm RF output power and inverted-F PCB antenna. It operates across –40°C to +85°C and supports ultra-low-energy operation down to 1.71 V supply.
Mainboard-level subsystems include SEGGER J-Link debugger with USB/Ethernet host interfaces, real-time AEM current/voltage monitoring, PTI for packet-level RF analysis, and Simplicity Studio–managed virtual UART - all accessible via standardized connectors (Simplicity, Mini Simplicity, ARM Debug+ETM) and routed through an on-board board controller multiplexer.

FAQ
What is included in the SLWSTK6021A kit?
The SLWSTK6021A includes one BRD4002A Wireless Pro Kit Mainboard, one BRD4182A EFR32xG22 2.4 GHz 6 dBm radio board, one BRD4183A EFR32xG22 QFN32 radio board, and one 10-pin 1.27 mm IDC debug cable. Kit contents may vary by revision; SLWSTK6021A Rev. B00 ships with BRD4002A, while earlier revisions may include BRD4001A.
Does SLWSTK6021A support Bluetooth LE and Matter development?
Yes, SLWSTK6021A supports Bluetooth LE and Matter-over-Thread development out of the box via Simplicity Studio SDKs and pre-certified software stacks. The EFR32MG22 SoC on the included BRD4182A radio board is qualified for Bluetooth 5.2, Zigbee 3.0, Thread 1.3, and Matter 1.0, with hardware-accelerated cryptography and secure boot.
Can SLWSTK6021A be used to debug external target hardware?
Yes, SLWSTK6021A supports external target debugging via multiple interfaces: Simplicity Connector, Mini Simplicity Connector, ARM Debug+ETM header, and BRD8010A debug adapter. All provide SWD, PTI, VCOM, and AEM monitoring - with VMCU rail current measurements preserved when powering the target externally.
What is the role of the BRD4182A radio board within SLWSTK6021A?
The BRD4182A radio board hosts the EFR32MG22C224F512IM40 SoC and provides the core 2.4 GHz RF functionality for SLWSTK6021A - including the inverted-F PCB antenna, 6 dBm transmit power, and matching network. It plugs into the mainboard's radio slot and routes all SoC I/Os to breakout pads and the EXP header.
How does the Advanced Energy Monitor (AEM) function in SLWSTK6021A?
The AEM in SLWSTK6021A measures real-time current draw on the VMCU rail (1.71–3.8 V range) with µA resolution and correlates energy consumption directly to source code lines in Simplicity Studio. It supports both on-board radio board operation and external target debugging - but only monitors VMCU, not 3V3 or 5V rails.
