Wio Tracker L2 Introduction

pir

The Wio Tracker L2 Series is a highly extensible Meshtastic® node featuring LoRa (862–930 MHz), the ESP32S3 for efficient processing, and an L76K GPS module for accurate location tracking. Designed for flexibility, it supports QSPI touch screen, E-Ink displays, TF Card, as well as solar panels and battery power, making it ideal for a wide range of IoT and off-grid applications.

Features​

  • 3.2'' High-Quality Touchscreen: Featuring a 320×240 high-clarity display with switchable MUI and Base UI, it delivers smooth on-device interaction for messaging, mapping, and control—without a mobile phone.

  • ESP32S3 Powered, Ready to Build On: Powered by the dual-core ESP32-S3 with Wi-Fi and Bluetooth LE, L2 Pro provides a flexible platform for UI customization, feature development, and open-source applications.

  • Offline Maps with GNSS Positioning: Pre-download offline maps to a MicroSD card and view your real-time GNSS location directly on the device, even without cellular coverage or internet access.

  • 3000mAh Long-Lasting Battery: Supports extended daily use with reduced charging frequency; operates within -10°C to 55°C conditions.

  • Easy to Carry, Flexible Placement: A foldable antenna improves portability, and the 1/4" mounting interface supports flexible placement with compatible accessories.
