Embedded and hobbyist {hardware} specialist LILYGO has launched a brand new model of its T-Watch wearable improvement platform dubbed the T-Watch Extremely — that includes an AMOLED show, built-in LoRa transceiver, and an Espressif ESP32-S3 microcontroller.
LILYGO isn’t any stranger to watch-style wearables: the corporate launched its authentic TTGO T-Watch again in 2019, earlier than updating it a yr later with a slimline redesign dubbed the T-Watch-2020. A yr after that, the T-Watch 2020 V3 was launched, including a microphone to the design — however the brand new T-Watch Extremely is a substantial improve over all the pieces that has come earlier than.

The brand new smartwatch improvement platform, delivered to our consideration by Linux Gizmos, is predicated on the extra highly effective Espressif ESP32-S3, giving it a pair of Tensilica Xtensa LX7 cores working at as much as 240MHz plus 8MB of pseudo-static RAM (PSRAM) and 16MB of quad-SPI program flash, with a mciroSD Card slot for storage enlargement. That is hidden behind the watch’s show, a 2.06″ AMOLED touchscreen with a 410×502 decision — each greater and brighter than the 1.54″ LCD touchscreen of the T-Watch-2020 V3.
There’s been a giant improve on the connectivity entrance, too. The Bluetooth 5.0 Low Vitality and single-band 802.11b/g/n Wi-Fi radios of the sooner watches are nonetheless intact, however LILYGO has chosen so as to add a Semtech SX1262 LoRa transceiver — that means, ought to the firmware be ported to the platform, the potential for the watch for use as a node on the Meshtastic community-driven mesh and different LoRa-based networks. There’s additionally a u-blox MIA-M10Q World Navigation Satellite tv for pc System (GNSS) receiver and a six-axis Bosch BHI260AP inertial measurement unit with built-in machine studying core.

Different options embrace a microphone, amplified speaker, haptic vibration motor, Close to Discipline Communication (NFC) transceiver, and — as you’d hope to search out in a tool that’s, when all is claimed and achieved, a watch — a real-time clock. An inner 1,100mAh battery retains the machine ticking, with a USB Kind-C connector for charging and information; programming is supported through the Arduino IDE, MicroPython, and Espressif’s personal ESP-IDF.
The T-Watch Extremely is listed on the LILYGO web site now at $78.32, although on the time of writing was exhibiting as out-of-stock; extra info is accessible on the product’s GitHub web page.
