Product details

Overview

STM32WBA55G-DK1 from STMicroelectronics is a Discovery kit built around the STM32WBA55CGU7 ultra-low-power wireless MCU featuring Arm® Cortex®-M33 core, Arm® TrustZone®, 1 Mbyte Flash, 128 Kbytes SRAM, and integrated 2.4 GHz Bluetooth® 5.4/LE Audio RF transceiver on MB1803 board. It includes OLED display, digital microphone, user joystick, LED, USB-C, ARDUINO® Uno V3 and STMod+ expansion headers, and on-board STLINK-V3EC debugger.

For engineers reviewing the STM32WBA55G-DK1 datasheet, STM32WBA55G-DK1 pinout, STM32WBA55G-DK1 application, or STM32WBA55G-DK1 equivalent, this kit enables rapid prototyping of Bluetooth LE Audio, Matter border router, Zigbee®, and ultra-low-power industrial/medical wireless sensor nodes with full security (TrustZone), debug, and software stack support via STM32CubeWBA.

Technical Context

The STM32WBA55G-DK1 integrates two PCBs: MB1802 (mezzanine) and MB1803 (MCU RF board), with the latter housing the STM32WBA55CGU7 in UFQFPN48 package and a 2.4 GHz RF transceiver compliant with Bluetooth® Low Energy v5.4 and LE Audio isochronous channels. It supports Matter over Thread and Zigbee® protocols via certified software stacks.

Power architecture includes flexible sourcing from ST-LINK USB VBUS or external battery/jack inputs, with dedicated 3.5 mm stereo jacks for analog audio I/O and MIPI10/Tag-Connect™ 10-pin debug interface. The STLINK-V3EC provides mass storage, Virtual COM port, and SWD debugging without external tools.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	Arm® Cortex®-M33 with TrustZone®, MPU, FPU, and DSP extension - enables secure, real-time signal processing and isolated execution environments
Memory	1 Mbyte Flash + 128 Kbytes SRAM - sufficient for dual-image OTA updates and concurrent BLE Audio + Matter stack execution
RF Capability	2.4 GHz transceiver supporting Bluetooth® 5.4, LE Audio (Isochronous Channels), Matter (as Border Router), and Zigbee® - validated protocol interoperability out-of-box
Debug Interface	On-board STLINK-V3EC with USB re-enumeration (mass storage, VCP, debug) - eliminates need for external debugger during development
Expansion	ARDUINO® Uno V3 + STMod+ + Grove + MIPI10 + Tag-Connect™ - enables hardware modularity across sensor, audio, and connectivity add-ons
Audio I/O	Digital microphone + stereo 3.5 mm jacks (input/output) + OLED display - supports end-to-end LE Audio capture, processing, and playback demonstration

FAQ

Does the STM32WBA55G-DK1 include pre-flashed firmware?

Yes - demonstration software for peripherals (OLED, microphone, joystick, BLE advertising) is preloaded in the STM32WBA55CGU7's Flash memory. Full source code and updated binaries are available in the STM32CubeWBA package on www.st.com, supporting immediate standalone evaluation without initial programming.

Can the STM32WBA55G-DK1 be used as a Matter border router?

Yes - the kit supports Matter over Thread via certified software stacks in STM32CubeWBA. Its dual-band capability (2.4 GHz BLE + Thread) and TrustZone-secured network stack enable it to function as a certified Matter border router when configured with appropriate firmware and Thread RCP firmware on the companion NCP device.

What IDEs and toolchains are officially supported?

IAR Embedded Workbench® (Windows only), Keil MDK-ARM (Windows only), and STM32CubeIDE (multi-OS) are fully supported. All integrate with the STLINK-V3EC debugger and STM32CubeWBA HAL libraries, enabling seamless build-debug-deploy workflows for BLE Audio, Matter, and custom wireless applications.

Is external antenna support available on the STM32WBA55G-DK1?

No - the MB1803 MCU RF board uses an integrated PCB antenna optimized for 2.4 GHz operation. There is no U.FL/IPX connector or RF test point; however, the board layout includes matching network access points for advanced RF characterization if required during design validation.
