Qualcomm Snapdragon W5+ and W5 wearables platforms promise higher efficiency and performance

Snapdragon W5+ Block Diagram

It’s been a while since Qualcomm released a new platform for wearables. More exactly, the Snapdragon 4100 platform was announced a little over two years ago, and now Qualcomm has just introduced the Snapdragon W5+ and W5 Gen 1 platforms with up to 50% longer battery, twice the performance, and 30 percent smaller size. Just like the Snapdragon 4100, the Snapdragon W5 comes with four Arm Cortex-A53 processor (SW5100), but is clocked at 1.7 GHz and manufactured with a 4nm process, while the always-on (AON) co-processor is upgraded from a Cortex-M0 chip to the QCC5100 Cortex-M55 chip manufactured with a 22nm process.     Snapdragon W5+/W5 specifications: W5100 SoC CPU – Quad-core Cortex-A53 processor @ up to 1.7 GHz GPU – Qualcomm Adreno A702 @ up to 1 GHz with OpenGL ES 3.1 API support DSP – Qualcomm Hexagon DSP V66K System Memory – 16-bit LPDDR4 up to 2,133 MHz […]

BP Doctor PRO review – A 2-in-1 smartwatch and blood pressure monitor

YHE BP Doctor Pro 2-in-1 smartwatch & blood pressure monitor

So far, If I wanted to monitor my blood pressure monitor and overall fitness, I’d use a Bluetooth blood pressure monitor (Koogeek BP2) plus a fitness tracker/smartwatch such as Weloop Key S3. It does the job, but WearWiz has come up with something much more compact with the BP Doctor Pro 2-in-1 device that acts as both a smartwatch/fitness tracker and a blood pressure monitor, and at $299, offers a cheaper alternative to the $500 FDA-approved Omron Heartguide. The company sent a sample to CNX Software for review, so we’ll have a look at the device and accessories, the Android app, and features such as blood pressure monitoring, HRM, SpO2 level monitoring, and more. The review is rather long, so if you are short on time, you may want to check the two sections: Blood pressure monitoring with BP Doctor PRO smartwatch Conclusion with Pros and Cons BP Doctor PRO […]
