MicroMod modular ecosystem offers M.2 microcontrollers cards and carrier boards

MicroMod Processor Boards

MicroMod is a modular interface ecosystem for quick embedded development and prototyping. MicroMod comes with two components, that is a microcontroller “processor board” and a carrier board. PC industry’s M.2 connector is the interface between these two components. The carrier boards are for the usage of various peripherals and the processor board act as the brain of the application system.  MicroMod processor board has a dimension of 22×22 mm that can be easily fitted on the carrier boards. Although, the original M.2 standard was dedicated to swapping out peripherals where a user could swap one component with the other one. The MicroMod standard is for swapping out microcontrollers according to the functional and application requirements.  MicroMod Processor Boards Artemis Processor Board comes with an Ambiq Apollo 3 Blue Arm Cortex-M4F with BLE 5.0 running up to 96MHz and a power rating of less than 5mW. It also supports the TensorFlow […]

Qualcomm unveils QCC305x/QCC3056 TrueWireless, Bluetooth LE Audio-ready SoC for earbuds

Qualcomm QCC305x TrueWireless Bluetooth LE Audio SoC

Qualcomm has some SoC families specifically designed for Bluetooth headphones, headsets, & earbuds, and we very recently covered the cute Qualcomm QCC5141 Earbud reference design made to help manufacturers design and launch earbuds with support for TrueWireless Mirroring and Hybrid ANC. The company has now introduced another family with the QCC305x SoC series aiming to “bring premium True Wireless earbud features to a broad range of tiers” such as Qualcomm Adaptive Active Noise Cancellation (ANC) and wake word activated voice assistant, as well as support for the upcoming Bluetooth LE audio standard. The first and only member of QCC305x family at this time is QCC3056 with the following key features and specifications: CPU – 32-bit programmable application core clocked at up to 80 MHz DSP – 2x Qualcomm Kalimba DSP @ 120 MHz with 112kB program RAM, 448kB data RAM Storage – External flash  Connectivity Bluetooth 5.2 qualified BR, EDR, […]

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 […]
