STM32WB5MMG Wireless Module

The STM32WB5MMG (STM32) is a wireless microcontroller module by STMicroelectronics. It is a compact ultra-low-power module that allows customers to design 2-layer PCBs and integrates everything up to the antenna, including an IPD (integrated passive device) for reliable antenna matching in order to reduce the overall costs. The STM32 wireless module is compatible with BLE (Bluetooth Low Energy) 5.0, OpenThread, Zigbee 3.0, dynamic and static concurrent modes, and 802.15.4 proprietary protocols. It also supports simultaneous dual-protocol mode that allows IEEE 802.15.4 radio-based protocols like Zigbee 3.0 and OpenThread for direct connection with any BLE device. Overview of STM32 Wireless Module The STM32 wireless module is a SiP-LGA86 package (System in Package Land Grid Array)  with various external components including:  STMicro STM32WB55 Cortex-M4/M0+ wireless MCU LSE crystal  HSE crystal Passive components for SMPS  Antenna matching and antenna  IPD for RF matching and harmonics rejection Key Features of STM32 Wireless Module Dedicated […]

HotDive converts your smartphone into a dive computer and underwater camera (crowdfunding)

Hotdive smartphone diving

Many recent phones are fitted with a pretty good camera, and some are waterproof, but not quite enough to go snorkeling or diving. If you could, your phone could also double as a dive computer, and that’s exactly what HotDive provides: a waterproof enclosure for your smartphone allowing you to dive up to 80 meters deep, and convert your phone in a dive computer, underwater camera, and fill light at a fraction of the cost of specialized diving equipment. HotDive enclosure includes an independent auto-pump air extraction system creating a vacuum for your smartphone to make sure all photos are clear of fog, as well as a fill light to take clear photos even during night dives. The fill light is made of CREE LED lights delivering 800 lumens, and providing with 130° illuminance and 5800-6500K sunlight-like color temperature. The HotDive Pro version includes hardware to create a built-in dive […]

Qualcomm QCC5141 Earbud reference design supports TrueWireless Mirroring and Hybrid ANC

qualcomm qcc5141 earbud reference design

Qualcomm has recently unveiled an earbud reference design based on the company’s QCC5141 low-power premium-tier Bluetooth SoC that supports TrueWireless Mirroring and Hybrid Active Noise Cancellation (ANC). What are TrueWireless Mirroring and Hybrid ANC? Qualcomm TrueWireless Mirroring technology relies on only one earbud to maintain the Bluetooth connection with the smartphone, while the secondary bud mirrors the connected bud.  If the connected earbud is removed, the secondary earbud assumes the connection with zero interruption. The technology enables both a better, more stable connection and lower power consumption Hybrid Active Noise Cancellation (ANC) is designed to provide high-quality immersive experiences and enable natural leak-through of noise to allow for awareness of surroundings. Qualcomm ANC is fully integrated into this QCC5141 chip to reduce the complexity, cost, and PCB space of adding ANC to earbuds and hearables. QCC5141 Earburd Reference Design Key features and specifications: WiSoC – Qualcomm QCC5141 single-chip Bluetooth SoC […]
