Heltec Wireless Tracker V2 ESP32-S3 LoRa GPS 868MHz

The Heltec Wireless Tracker V2 is a compact development board based on the ESP32-S3FN8 microcontroller, combining communication standards such as Wi-Fi, Bluetooth, LoRa, and GNSS into a single device. It features the SX1262 LoRa chip and the UC6580 GNSS chip for satellite navigation. With an integrated power amplifier, the board achieves a maximum transmission power of 28±1 dBm, and the LNA can be bypassed without affecting reception performance. The maximum reception sensitivity is -134 dBm. The GNSS module supports multi-system positioning via GPS, GLONASS, BDS (BeiDou), Galileo, NAVIC, and QZSS. Standard LDS antennas for 2.4 GHz and GNSS are included, significantly reducing the device's size. The board includes an integrated lithium battery management system with charging and discharging management, overcharge protection, battery level detection, and automatic switching between USB and battery power. The USB-C interface offers comprehensive voltage regulation, ESD protection, short-circuit protection, and RF shielding. The Wireless Tracker V2 is compatible with Meshtastic, MeshCore, and LoRaWAN and supports the Arduino development framework, ESP32-IDF, PlatformIO, and MicroPython. Additional connectors are available for an external LoRa antenna (IPEX 1.0), an external GNSS antenna (IPEX 1.0), a solar panel (SH1.25), and 2×18 header pins with a 2.54 mm pitch.

Features:

• Triple communication via Wi-Fi, Bluetooth LE, and LoRa enables versatile connectivity in a single board.
• The integrated power amplifier achieves a maximum transmission power of 28±1 dBm for long-range communication.
• The GNSS module supports six satellite systems for precise multi-system positioning.
• LDS antennas for 2.4 GHz and GNSS are integrated directly on the board, significantly reducing the overall size.
• The integrated battery management system enables mobile operation with lithium batteries and optional solar panels.
• Compatibility with Meshtastic, MeshCore, and LoRaWAN allows deployment in various mesh and IoT networks.

Use Cases:

• Building a Meshtastic mesh network for off-grid communication in remote areas.
• GPS-based asset tracking for monitoring the location of vehicles or equipment.
• Person tracking for outdoor activities such as hiking or mountaineering.
• Prototyping LoRaWAN sensor nodes for IoT applications in environmental monitoring.
• Mobile mesh node with solar power for autonomous long-term deployments.
