Product details
Overview
NUCLEO-WB09KE from STMicroelectronics is a Bluetooth® Low Energy development board built around the STM32WB09KEV6TR ultra-low-power wireless MCU, featuring an Arm® Cortex®‑M0+ core, 512 Kbytes flash, 64 Kbytes SRAM, and integrated 2.4 GHz RF transceiver compliant with Bluetooth® v5.4 - used for rapid prototyping of BLE sensor nodes and edge-connected IoT endpoints.
For engineers reviewing the NUCLEO-WB09KE datasheet, NUCLEO-WB09KE pinout, NUCLEO-WB09KE application, or NUCLEO-WB09KE equivalent, this board delivers out-of-box debugging via ST-LINK-V3EC, Arduino Uno V3 and ST morpho expansion headers, USB Type-C® connectivity, and full STM32CubeWB0 software support across IAR, Keil MDK-ARM, and STM32CubeIDE.
Technical Context
The NUCLEO-WB09KE integrates two independent execution environments: the Cortex-M0+ core handles BLE protocol stack execution (host + controller), while application firmware runs on the same core in dual-core mode via time-sliced partitioning - enabling concurrent radio operation and user logic without external co-processor. It supports BLE advertising, scanning, and connection states with -96 dBm RX sensitivity and +4 dBm TX output power.
Power architecture includes flexible sourcing (USB VBUS or external supply), ultra-low-power run modes (down to 1.28 µA in Stop2 with RTC and 32 kHz LSE), and hardware-accelerated AES-128/256 and PKA for secure firmware updates and device authentication - critical for certified IoT deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| MCU Core | Arm Cortex-M0+ @ 64 MHz - single-cycle GPIO, low-latency interrupt response for real-time BLE event handling |
| Memory | 512 KB Flash / 64 KB SRAM - sufficient for BLE stack + application firmware with OTA update partitioning |
| RF Transceiver | 2.4 GHz BLE v5.4 compliant - supports LE Audio, Long Range, and extended advertising with PCB antenna |
| Debug Interface | On-board ST-LINK-V3EC - provides mass storage, Virtual COM port, and SWD debug without external tools |
| Expansion Headers | Arduino Uno V3 + ST morpho - exposes all STM32WB09KE I/Os including analog inputs, timers, and crypto peripherals |
| Power Options | USB Type-C® VBUS or external 1.71–3.6 V - enables battery-powered evaluation with voltage monitoring and brown-out detection |

FAQ
Does NUCLEO-WB09KE support Bluetooth mesh networking?
No. The board implements the Bluetooth SIG-certified LE Controller + Host stack per v5.4 but does not include the Bluetooth mesh profile stack. Mesh functionality requires additional third-party or custom implementation atop the provided BLE foundation - ST's official software packages do not deliver mesh out-of-the-box.
Can the onboard ST-LINK-V3EC program external STM32 devices?
Yes. The ST-LINK-V3EC debugger supports external target programming via SWD interface using the ST morpho header's SWCLK/SWDIO pins. It operates as a standalone programmer when the board's JP2 jumper is set to "External" mode, enabling firmware flashing and debug of other STM32 MCUs without modifying the NUCLEO-WB09KE's own target device.
What is the maximum operating temperature range for reliable RF performance?
The STM32WB09KEV6TR MCU is rated for -40°C to +85°C ambient operation. RF performance - including TX power stability and RX sensitivity - remains within specification across this full range, verified per Bluetooth SIG test requirements in DB5244 and RM0474 reference manual sections on RF characteristics and thermal derating.
Is the PCB antenna pre-tuned and FCC/CE certified?
Yes. The onboard PCB antenna is factory-tuned and included in the STMicroelectronics FCC ID 2AHPN-NUCLEOWB09KE and CE RED certification scope. Radiated emission and receiver sensitivity test reports are published in the board's declaration of conformity (DoC), confirming compliance for end-product integration without additional antenna requalification.
