Beacon W5+ SoM – A tiny (27x15mm) Qualcomm Snapdragon W5+ System-on-Module for wearables

Tiny Snapdragon W5+ System-on-Module

Beacon EmbeddedWorks’ W5+ SoM is an ultra-compact (27×15 mm) system-on-module powered by the Qualcomm Snapdragon W5+ platform for wearables with a quad-core Cortex-A53 processor, a co-processor with an Arm Cortex-M55 core and an Ethos U55 ML accelerator, and WiFi 4 and Bluetooth 5.3 connectivity. The Snapdragon W5/W5+ wearables platforms were introduced in the summer of 2022, but so far, all I could find was a $2,000 devkit (TurboX W5+) suitable for ODM/OEM manufacturers. The upcoming Beacon W5+ SoM will be one of the first hardware solutions based on the Snapdragon W5+ platform designed for commercial applications. Beacon W5+ specifications: Platform – Snapragon W5+ SW5100P-0 SoC CPU – Quad-core Cortex-A53 processor @ up to 1.7 GHz GPU – Qualcomm Adreno A702 @ up to 1,010 MHz with OpenGL ES 3.1, Vulkan 1.0, OpenCL 2.0 API support DSP – Dual Qualcomm Hexagon DSP V66K ISP – Dual ISP VPU 1080p30 Video Decode […]

LILYGO T-Deck Pro – An ESP32-S3 LoRa messenger with e-paper touch display, keyboard, and 4G LTE or audio codec option

LILYGO T-Deck Pro

LILYGO T-Deck Pro is a LoRa messenger based on an ESP32-S3 WiFi 4 and Bluetooth 5.x SoC, and offered with a 3.1-inch e-paper display with touchscreen, a Blackberry-like QWERTY keyboard, a GPS module, speaker, microphone, and a 3.5mm audio, as well as IMU and light sensors. It builds upon the T-Deck Plus design, but replacing the 2.8-inch IPS display with a 3.1-inch e-paper display allows for a slimmer design and should offer longer battery life despite the smaller 1,400 mAh battery used in the new model. Two versions of the T-Deck Pro are available: one with a Simcom 4G LTE modem and a cheaper one with a PCM5102A audio codec. LILYGO T-Deck Pro specifications: SoC –  ESP32-S3FN16R8 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash Storage – MicroSD card […]

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

7.5inch NFC Powered e Paper V2 side view

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock. However, precise NFC positioning is required for updates. These features make it ideal for shelf labels, equipment tags, and other applications.

SparkFun Air Quality PM1/PM2.5/PM10 Sensor features Bosch’s BMV080, the world’s smallest particulate matter sensor

Sparkfun BMV080 PM2.5 sensor

SparkFun’s “Air Quality PM1/PM2.5/PM10 Sensor – BMV080 (Qwiic)” is breakout board for the Bosch Sensortec BMV080 particulate matter sensor which the German company claims is the world’s smallest and 450 times smaller in volume than any comparable device on the market. It’s summer in Thailand right now, and besides scorching temperatures of over 40°C during the day, it’s also smog season with high PM 2.5 values and frequent alerts not to exercise outdoors. We usually get the Air Quality Index (AQI) from apps like IQAir AirVisual, or people can install air quality monitors in fixed locations to get local readings. But the small size (4.4 x 3.0 x 20 mm³) of the Bosch BMV080 can enable PM2.5 monitoring in wearables or other small devices like the PurpleAir PIXEL USB dongle. SparkFun Air Quality PM1/PM2.5/PM10 Sensor – BMV080 (Qwiic) specifications: Sensor – Bosch Sensortec BMV080 PM Mass Concentration Range: 0 to […]
