Product details

Overview

SLWSTK6101B from Silicon Labs is a Bluetooth® Low Energy development kit based on the BGM111 wireless module, integrating a 32-bit ARM Cortex-M4 core, 256 kB flash, 32 kB RAM, +8 dBm TX power, -92 dBm RX sensitivity, and an onboard chip antenna - enabling rapid prototyping of battery-powered IoT sensors and commercial accessories.

For engineers reviewing the SLWSTK6101B datasheet, SLWSTK6101B pinout, SLWSTK6101B application, or SLWSTK6101B equivalent, this page delivers verified hardware interface details, energy mode behavior (EM0–EM4), Bluetooth stack integration status, UART/LEUART/I²C peripheral support, and real-world use-case validation for health, industrial, and retail BLE deployments.

Technical Context

The SLWSTK6101B is a complete evaluation platform-not a component-featuring the BGM111A256V2 module with integrated EFR32BG1 SoC, pre-flashed Bluetooth SDK 1.0.0 NCP firmware, and hardware interfaces to host MCU, sensors, and debug peripherals. It supports BGAPI serial communication over UART and provides access to all 25 GPIOs, analog peripherals (ADC, ACMP, IDAC), and low-energy timers (LETIMER, CRYOTIMER, RTCC).

Its architecture enables autonomous operation in EM2 Deep Sleep (2.5 μA) and EM3 Stop (2.1 μA) modes while retaining RAM and RTC functionality, with hardware crypto acceleration (AES-128/256, SHA-2, ECC) and PRS-driven peripheral coordination eliminating CPU wakeups for sensor polling or PWM generation.

FAQ

What is the SLWSTK6101B used for?

The SLWSTK6101B is a Blue Gecko Bluetooth Low Energy Module Wireless Development Kit that enables rapid prototyping and firmware validation using the BGM111A256V2 module. It supports BGAPI-based UART communication, on-board debugging via Serial Wire Debug, and direct connection to sensors or host MCUs. The SLWSTK6101B includes expansion headers for custom peripherals and integrates the full Bluetooth stack required for certified BLE product development.

Does the SLWSTK6101B include the BGM111 module?

Yes, the SLWSTK6101B contains the BGM111A256V2 module with pre-installed Bluetooth SDK 1.0.0 NCP firmware, enabling immediate BGAPI serial communication over UART. The module features a 32-bit ARM Cortex-M4 core, 256 kB flash, 32 kB RAM, integrated chip antenna, and full peripheral access - all accessible through the SLWSTK6101B's standardized WSTK interface and expansion headers.

What power modes does the SLWSTK6101B support via its BGM111 module?

The SLWSTK6101B leverages the BGM111's five energy modes: EM0 Active (63 μA/MHz), EM1 Sleep, EM2 Deep Sleep (2.5 μA with full RAM retention and RTCC running), EM3 Stop (2.1 μA with state/RAM retention), and EM4 Hibernate. These are accessible via Silicon Labs' Simplicity Studio and validated in the SLWSTK6101B's reference designs for ultra-low-power sensor nodes and battery-operated BLE accessories.

Can the SLWSTK6101B be used for FCC/CE certification testing?

The SLWSTK6101B itself is not a certified end-product but serves as a pre-certified reference platform: the embedded BGM111A256V2 module carries full FCC, IC, CE, UKCA, MIC, NCC, and KC certifications. Engineers use the SLWSTK6101B to validate application-layer firmware, antenna matching, and system-level RF performance before final PCB layout - significantly reducing certification risk for derivative designs based on the same module.

What debug and programming interfaces does the SLWSTK6101B provide?

The SLWSTK6101B provides Serial Wire Debug (SWD) for full-core debugging and flash programming of the BGM111 module, plus UART-based BGAPI communication for runtime command/response interaction. It supports Simplicity Studio IDE integration, energy profiling tools, and packet trace analysis - all accessible without external adapters. Firmware updates for the SLWSTK6101B's BGM111 module can be performed in-system via UART or SWD.
