T-Watch Ultra

The Ultimate Smartwatch for Makers, Developers & Explorers

Overview

Dare to explore the frontier of IoT and wearable development with the T-Watch Ultra — a powerhouse marrying a vibrant AMOLED display, robust ESP32-S3 processing, LoRa connectivity, and precision GNSS in a rugged, compact form factor. Designed for the creative technologist, outdoor enthusiast, and hardware hacker alike—this is more than a timepiece.

Key Highlights

1. Performance & Processing Power

• ESP32-S3 Dual-Core Cortex-LX7, running up to 240 MHz, paired with 16 MB Flash and 8 MB PSRAM empowers advanced tasks—from AI/ML experiments to multi-sensor fusion.

• Compatible with Arduino IDE, MicroPython, and Espressif ESP-IDF, offering flexibility for beginners and experienced developers alike.

2. Vibrant AMOLED Display & Intuitive Controls

• Enjoy a vivid 2.06-inch AMOLED touchscreen with 502 × 410 resolution, delivering crystal-clear visuals and great outdoor readability.

• Navigate smoothly using two side buttons and an integrated rotary encoder—perfect for tweaking settings or scrolling through custom UIs.

3. Multi-Protocol Wireless Connectivity

• LoRa (SX1262) for long-range, low-power communication; ideal for mesh networks like Meshtastic or IoT sensor grids.

• Built-in Wi-Fi 802.11 b/g/n, Bluetooth 5.0 LE, NFC, and u-blox MIA-M10Q GNSS (GPS/GLONASS) cover every wireless and positioning need.

4. Rugged, Ready for Adventure

• Built tough: IP67 waterproof, MIL-STD-810H rated, and reinforced with titanium—engineered for reliability in extreme environments.

• A 1,100 mAh battery delivers ~23 hours off-grid (GPS off) or ~19 hours (GPS on), with USB-C charging and optional solar enhancements expanding runtime possibilities.

5. Versatile Sensors & Expansion Capabilities

• Includes Bosch BHI260AP IMU featuring a built-in ML core for advanced motion tracking.

• Expand with microSD slot (up to 32 GB), Qwiic/STEMMA QT connectors, and TF-card-boot support—perfect for add-ons or data logging.

• Additional hardware: microphone, amplified speaker, haptic motor, RTC—making it a full-featured wearable development hub.

Why T-Watch Ultra Stands Out

• Rugged artisanship meets developer-grade hardware: perfect for creators who need durability without compromising on programmability or performance.

• All-in-one edge device: GPS, LoRa, Wi-Fi, BLE, sensors—a single watch that handles multiple use cases and power modes seamlessly.

• Customization-friendly: Open firmware ecosystems like Meshtastic and Arduino Toolkit—with growing community support—unlock endless possibilities.

• Compact brilliance: A surprisingly sleek design packed with advanced features usually found in bulky wearables.
