Lilygo TTGO T-Watch-2020 is a Nicer Looking Arduino Programmable ESP32 Watch

We’ve covered several ESP32 watches over the last year include TTGO T-Wristand, Watchy, and DSTIKE ESP32 watch. Those don’t really have the nicest looking design, and some people complained about various shortcomings including the difficulty to customize/program the watch. Last year, Lilygo introduced TTGO T-Watch smartwatch that, due to support for expansion boards, was relatively thick, but at least documentation and Arduino code samples can be found on Github. The company has now launched a slicker version with Lilygo TTGO T-Watch-2000. TTGO T-Watch-2020 specifications: SoC – Espressif ESP32 dual-core wireless processor with 520KB SRAM System Memory – 8MB PSRAM Storage – 16MB QSPI flash Display – 1.54-inch LCD capacitive touch screen Audio – Class-D amplifier, buzzer Connectivity – 802.11b/g/n WiFi 4 and Bluetooth 5.1 via ESP32 Sensors – BMA423 three-axis accelerometer with built-in step counting algorithm, activity recognition / tracking, advanced gesture recognition. Misc – Power button (round), PCF8563 RTC […]

NFC Wireless Charging Coming Soon to IoT Devices and Wearables

NFC is better known for contactless payment and transferring contacts, but one interesting feature is the ability to provide power as we’ve recently seen with batteryless NFC powered E-paper displays. The current NFC implementations can only provide a limited amount of power, but the NFC Forum has recently approved the Wireless Charging Specification that enables wireless charging of small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. One watt is not as much as other similar technologies, but NFC wireless charging (NFC WLC) should be quite more cost-effective since device-specific wireless chargers are not needed. Just take a phone or charger with NFC WLC and all compliant devices could be charged that way. The specification is free to download for NFC Forum members but must be purchased by others. There’s still short abstract available: Wireless […]

Omnichip Devkit 2 Features Nordic nRF52832 based zGlue ZiP Multichip Module

We first covered zGlue Integration Platform (ZiP) in 2018 when the company introduced its chip-stacking technology with a fitness tracker based on ZGZL1BA ZiP equipped with chips from Dialog Semiconductor, Analog Devices, Macronix, MCube and others. The concept is similar to SiP (System-in-Package), but zGlue claims the costs and lead times are much lower with the technology. Earlier this year, ZiP was back in the news thanks to Antmicro GEM custom RISC-V/Arm ASIC, and today, I was informed about zGlue Omnichip devkit 2 that is equipped with a ZiP of the same name, and that can be used to evaluate the technology. zGlue OmniChip ZiP zGlue OmniChip ZiP is a multichip module with the following ICs (aka Chiplets) and specifications: Nordic Semiconductor nRF52832 Cortex-M4F microcontroller with Bluetooth LE and NFC connectivity Texas Instruments BQ25120AYFPR battery charger, buck regulator Maxim Integrated MAX86140ENP+ optical pulse oximeter Texas Instruments TMP108AIYFFR temperature sensor Bosch […]

Adidas GMR Smart Insole Uses Google Jacquard for Enhanced Soccer Tracking

The Adidas GMR (pronounced Gamer) The new Adidas GMR tracking insole is connected to EA Sports FIFA Mobile for smartphone access and data gathering and uses Google’s Jacquard technology for touch-sensitive clothing. Past Shoes for Movement Tracking An athletic shoe that tracks steps was reported on in by CNX Software in the past, in the Xiaomi 90 Minutes Ultra Smart Running Shoe article. A Little About Project Jacquard Jacquard Technology which had been focused on touch-sensitive clothing is where a small device is woven into the item, like in the Levi Trucker Jacket. The tag tracks physical attributes and movements. Jacquard Technology was introduced by Google in 2015 and has been focused on expanding into other areas besides clothing. The tag is accessed through Bluetooth and can record a variety of motion, impact, and other physical aspects of life. The relay in the tag helps the app record the data […]

$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 […]

VOIXATCH Smartwatch Comes with a Detachable Bluetooth Headset (Crowdfunding)

As a Kickstarter project, VOIXATCH introduces the world’s first smartwatch device which puts essential features of all the devices we carry with us in one unit. This watch does everything that smartwatches do, plus it has a built-in Bluetooth headset. Other smartwatches can be used with Bluetooth headset, but VOIXATCH has a Bluetooth ring-look-like headset docked on it, and the headset can be detached anytime and used for phone calls or listening to the music. One can call it a headset smartwatch. Cool, huh? After Mobile World Congress 2019, where Voixatch demonstrated the watch, it is finally available for “purchase” on Kickstarter rewards starting at $179 and first batch delivery expected in June. VOIXATCH embodies LTE, GPS connectivity in an all-in-one truly wireless design that can be used with Google Voice. The watch can also be used as a cellular smartwatch with a bezel headset to make calls and stay […]

Google Glass Enterprise Edition 2 is Now Sold to Developers for $1,060 and Up

Powered by Snapdragon XR1 processor, Google Glass Enterprise Edition v2 has launched in May 2019, but at the time you had to contact Google Glass sales team or distributors to source one or more samples for your application, and there was no easy way to purchase the glasses online. But things have changed as the company realized they should make it easier for developers to build apps for the platform, and Google Glass Enterprise Edition 2 can now be purchased for around $1,060 from resellers such as Mobile Advance or SHI. At that price, it does not come with the “Titanium band” that appears required to make sure the glasses stay in place. So the price goes up to $1,195 (or $136 extra) if you want the Glass Enterprise Edition 2 Developer Kit with both the glass pod and the titanium band. This is not meant as a consumer device […]

V-Powerbuds Pro TWS Earbuds Support Heart Monitoring & Oxygen Tracking (Crowdfunding)

Vimai V-Powerbuds Pro Multi-function Sport Earbuds Vimai’s V-Powerbuds Pro TWS (True Wireless Stereo) earbuds are multi-function wireless earbuds. In the past, we had reported on the Misfit Specter Bluetooth earbuds that could track fitness input, such as steps, calories, and sleep duration. V-Powerbuds Pro also tracks heart rate, oxygen, and respiration, and supports online & offline voice control. The Component Basics The V-Powerbud Pro are TWS earbuds and have a built-in pulse oximeter to capture heart rate and oxygen levels right from within the ear. The hook design holds the earbuds tightly in place, within the ear, to get an accurate measurement independent of the effects of light. Other types of fitness tracking devices like those located on the wrist, can be affected by light. The Difference From Other Sport Earbuds Although the uses during exercise aspect of this wearable are probably more likely to be a selling point, the […]
