Arrow Electronics Lanza Módulos Inalámbricos IoT Sharky de Alta Eficiencia Energética

Arrow Electronics ha lanzado nueva línea de radio modules diseñados para accelerate IoT device development. Powered by STMicroelectronics' STM32WB55 wireless microcontroller, los modules —codenamed Sharky— combinan power-efficient dual-core performance con robust wireless stack. La Sharky family fue co-developed con Italian design studio Midatronics.

El STM32WB55 integra 2.4 GHz RF transceiver que soporta Bluetooth 5 (incluyendo BLE), Thread y Zigbee. Su dual ARM Cortex-M architecture entrega real-time secure application performance en 64 MHz Cortex-M4F core, mientras co-integrated Cortex-M0+ core maneja radio management y security tasks independently.

Dos base models, MDX-STWBP-01 y MDX-STWUP-R01, dan developers flexibility to choose between on-board PCB antenna o UFL connector para external antenna. Antenna-balun circuitry está built into the MCU. Las Sharkypro variants —MDX-STWBC-R01 y MDX-STWBW-R01— ofrecen chip antenna o no antenna option, respectivamente.

Con shutdown current de just 13 nA y 600 nA en standby (RTC y RAM powered), los modules son remarkably energy-efficient. Deliver receive sensitivity de −96 dBm, programmable RF output power, y draw only 4.5 mA during reception y 0 dBm during transmission. El STM32WB55 también proporciona hardware-based encryption, public-key authorization, true random number generator y secure customer key storage.

Ambos Sharky y Sharkypro modules vienen pre-installed con 32 MHz RF crystal y 32.7 kHz reference crystal required by the MCU, making them ready para immediate integration. Developers pueden further accelerate their projects usando ST's STM32Cube ecosystem, que incluye MCU configuration tools, middleware, peripheral drivers, connectivity libraries y RF monitoring tool. Physical dimensions son 16 × 27.25 mm para Sharky y 14.6 × 23 mm o 14.6 × 14.6 mm para Sharkypro.
