Arrow Electronics<\/a><\/strong> has introduced a family of radio modules to jump-start IoT-device design, leveraging the power-efficient dual-core performance of STMicroelectronics\u2019 STM32WB55 wireless microcontroller.\u00a0<\/p>\n\n\n\n

The Sharky modules were co-developed with Italian designer Midatronics.<\/p>\n\n\n\n

The STM32WB55 microcontroller (MCU) at the heart of these modules integrates a 2.4GHz RF transceiver supporting Bluetooth 5 (including BLE), Thread, and ZigBee stacks. <\/p>\n\n\n\n

Its dual Arm Cortex-M core architecture enables real-time secure application performance running on the 64MHz Cortex-M4F core, while concurrently managing the radio subsystem and security tasks on the co-integrated and completely independent Cortex-M0+.<\/p>\n\n\n\n

The Sharky modules, MDX-STWBP-01 and MDX-STWUP-R01, respectively give users the choice of an on-board PCB antenna or a UFL connector for attaching an external antenna. <\/p>\n\n\n\n

Balun circuitry for connecting the antenna is integrated in the MCU. Alternatively, the Sharkypro modules, MDX-STWBC-R01 and MDX-STWBW-R01 offer a choice of a chip antenna or no antenna, respectively.<\/p>\n\n\n\n

Compact and power-conscious, the modules draw 13nA in shutdown mode and 600nA in standby with the MCU real-time clock and RAM powered up. <\/p>\n\n\n\n

With -96dBm receive sensitivity and programmable RF output power, active current is also low at just 4.5mA receive and transmitting at 0dBm. <\/p>\n\n\n\n

Users can secure their devices on the IoT leveraging the MCU\u2019s hardware-based encryption, Public Key Authorisation (PKA) and Random Number Generator (RNG), with customer key storage to keep keys hidden.<\/p>\n\n\n\n

The modules come with the RF (32MHz) and 32.7kHz crystals required by the MCU already fitted and are ready to start work. <\/p>\n\n\n\n

Users can accelerate their projects by taking advantage of ST\u2019s STM32Cube development ecosystem, which provides MCU-configuration tools, middleware, and new extensions for the STM32WB55, including peripheral drivers, connectivity libraries, and a monitoring tool for RF testing.<\/p>\n\n\n\n

The Sharky modules measure 16mm x 27.25mm and the Sharkypro variants are 14.6mm x 23mm or 14.6mm x 14.6mm.<\/p>\n","protected":false},"excerpt":{"rendered":"
