$55 Watchy Smartwatch Combines ESP32 WiFi & Bluetooth SoC with E-ink Display

SQFMI has designed a (mostly) open-source hardware smartwatch based on an ESP32-S wireless module for WiFI and Bluetooth connectivity, and equipped with an E-ink display of 200×200 resolution. Watchy also comes with a BMA423 accelerometer, four buttons, a DS3231 real-time clock, and a vibration motor. The watch should last around 2 weeks on a charge. I mentioned the watch is “mostly” open source hardware because while the GERBER files, bill of materials (BoM) and the PDF schematics have been released on Github, the KiCAD schematics and PCB layout files have not so far. That still means you can understand the design, repair the design, or even make your own, but if you intended in modifying the design, you’d have some more work to do. Tom Fleet, writing for Hackster.io, does go through different sections of the schematics and explain what they do. One the software side, the watch can be […]

SDMC Unveils Amlogic S805Y Full HD Android TV 10 Media Box for Operators

The other day when I covered Amlogic A113L IoT/Smart audio processor, I did not realize I missed another processor from the company: Amlogic S805Y. It got brought to my attention today, as SDMC recently launched the “DV9038 Quad Core 2K Google Android TV Media Box” based on the processor that I initially thought was a cost-down version of Amlogic S805X Full HD SoC without Ethernet support since that’s the main difference between S905X2 and S905Y2 processors, but as we’ll see below my first assumption was wrong. DV9038 TV box specifications Let’s first check out what the box has to offer: SoC – Amlogic S805Y quad-core Arm Cortex-A53 processor @ up to 1.5GHz with penta-core Mali-450MP GPU up to 650MHz+ System Memory – 1GB DDR (2GB optional) Storage – 8GB eMMC flash (16GB, 32GB, 64GB optional) Video & Audio Output HDMI 2.0b with CEC, HDCP2.2, HDR 10, HLG HDR 3.5mm AV […]

ESP32-S2-Kaluga-1 “Multimedia” Development Board Comes with Touchscreen Display & Camera

ESP32-S2 secure WiFi processor based on Xtensa LX7 core was first unveiled in May 2019, before the datasheet was released, and the first development boards were showcased in September. The Coronavirus outbreak slowed down progress, but the company has now announced the start of mass production for ESP32-S2 SoC, ESP32-S2-WROVER & ESP32-S2-WROOM modules, and ESP32-S2-Saola-1 development board. So that means we should soon be able to buy any of those. Apart from improved security, ESP32-S2 chip also provides a USB OTG interface and interfaces for HMI (Human Machine Interface) solutions thanks to LCD & camera interfaces. So that’s probably why the company has developed ESP-S2 Kaluga-1 board with an LCD touchscreen display, touch panel, support for camera image acquisition, audio playback, and more. We do not have the full specifications at this stage, but here are some of the highlights of the board: LCD interfaces – SPI interface or 8-/16-/24-bit […]

Ampere Altra Announces 80-Core Arm Neoverse N1 Server Processor & Reference Designs

The first 64-bit Arm server processor was announced almost 9 years ago. Applied Micro X-Gene was found in several servers, and the company updated X-Gene family until it got bought by Ampere in 2018. The latter has now announced the first of their own design with Ampere Altra, an 80-core Arm Neoverse N1 server processor made for data centers. Ampere Altra specifications: Processor Subsystem 80x Arm v8.2+ 64-bit CPU cores up to 3.0 GHz with Sustained Turbo 64 KB L1 I-cache, 64 KB L1 D-cache per core, 1 MB L2 cache per core, 32 MB System Level Cache (SLC) 2x full-width (128b) SIMD Coherent mesh-based interconnect, distributed snoop filtering System memory 8x 72-bit DDR4-3200 channels ECC, Symbol-based ECC, and DDR4 RAS features Up to 16 DIMMs and 4 TB/socket System Resources Full interrupt virtualization (GICv3) Full I/O virtualization (SMMUv3) Enterprise server-class RAS Connectivity 128 lanes of PCIe Gen4 8 x8 […]

What’s the Cheapest Android Phone with NFC Support?

I have an Octopus payment card from Hong Kong using NFC technology, and I’d like to check its status, and if needed top it up to keep it valid. One way to do so is to install the Android app on an NFC enabled smartphone. However, none of my phones, including my current Xiaomi Mi A2 smartphone, support NFC. So I’d decided to look for the cheapest Android phone with NFC support that I could find since that’s the only feature I need, and the app is compatible with Android 4.0 or greater for now. Wileyfox Swift 2X – $75.90 I first went to GearBest to check out for NFC phones, as the cheapest one of the lot is Wileyfox Swift 2X going for $75.90 shipped. The phone runs Android 8.1 on a Snapdragon 430 processor coupled with 3GB RAM and 32GB storage. It is equipped with a 5.2″ Full […]
