Description HELTEC Wireless Tracker V2 is a compact ESP32-S3 GPS LoRa node for GNSS tracking, Meshtastic field nodes, MeshCore tests, LoRaWAN prototypes and battery-powered telemetry projects. It is built around the ESP32-S3FN8 and integrates an SX1262 LoRa transceiver plus a UC6580 GNSS chip, so Wi-Fi, Bluetooth, LoRa and GNSS positioning are available on one small development board. The board is designed for mobile and outdoor IoT work where size, wireless range and location data matter. HELTEC lists a built-in PA with up to 28 +/- 1 dBm transmit power, receiving sensitivity down to -134 dBm, LDS antennas for both 2.4G and GNSS, USB-C, lithium battery management, solar input and exposed headers. That makes the Wireless Tracker V2 useful for personnel positioning, asset tracking, portable mesh nodes and LoRaWAN data collection. This product page keeps the item as a single SKU. The official product family supports LoRa band options, and this page documents the supported frequency ranges so buyers can confirm regional firmware and network plans before deployment. Features ESP32-S3FN8 with Xtensa 32-bit LX7 dual-core processor for embedded wireless applications. SX1262 LoRa radio for long-range communication and mesh experiments.

Asset tracking: use GNSS and LoRa for field trials, mobile equipment, demo kits and low-data-rate location projects. Personnel positioning: create portable location-aware nodes for lawful testing, events, field labs and education. LoRaWAN end node: test regional frequency plans, uplinks and sensor payloads with ESP32-S3 firmware. MeshCore projects: evaluate compact MeshCore nodes with onboard GNSS and battery support. Solar-assisted telemetry: combine the solar input, battery interface and LoRa link for outdoor sensor nodes. Embedded development: use the 2x20 headers, UART, I2C, SPI, ADC and touch resources for custom expansions. Product List Wireless Tracker V2 board 1 pc Spring LoRa antenna 1 pc SH1.25 x 2 battery connector 1 pc Pin header 2 pcs Other Content Firmware and bootloader note: if the board cannot flash firmware or the serial port cannot connect, HELTEC recommends entering bootloader mode by connecting USB, holding the USER key, pressing RST once, then releasing USER. A real data-capable USB-C cable is required. GNSS note: first GNSS fix may take time, especially indoors. Use an open outdoor location, keep the screen side toward the sky and avoid blocking the GNSS antenna with metal. If GNSS data remains at 0,0,0, HELTEC provides a UC6580 reset firmware resource in the Resources section. Antenna note: the development board uses LDS antennas by default. If an external GNSS antenna is needed, follow the official GNSS IPEX switching diagram and confirm the resistor position before modification. Board layout and component placement: The official layout image helps identify the ESP32-S3FN8 MCU, SX1262 LoRa section, UC6580 GNSS area, USB-C interface, display, antenna areas and exposed expansion points before firmware or enclosure work.Display, LoRa and GNSS front view: This view shows how the Wireless Tracker V2 combines a compact front display area with GNSS, LoRa and portable tracker hardware in one small development node.USB-C, battery, solar and header details: The detail image is useful when checking USB-C power, lithium battery input, solar input, ESD and short-circuit protection, RF shielding and the 2x20 header layout.LDS antenna design: The 2.4G and GNSS antennas use LDS antenna design by default, helping reduce the device size for handheld nodes, asset trackers and compact field equipment.GNSS IPEX antenna switching note: The Wireless Tracker V2 uses the LDS GNSS antenna by default. The official GNSS IPEX diagram shows the resistor change needed when an external GNSS antenna is required.

Yes. The HELTEC Wireless Tracker V2 is designed for Meshtastic-compatible tracker and LoRa node projects. Select firmware and regional LoRa settings carefully before deployment. Does the board include GNSS? Yes. It integrates a UC6580 GNSS chip and uses a default LDS GNSS antenna, making it suitable for GPS/GNSS tracking projects. What frequency range should I use? The official family lists regional LoRa band support. Use the frequency plan that matches your country, firmware and network, such as 863-870MHz in many European contexts or 902-928MHz in US contexts. Can I connect an external GNSS antenna? Yes, but the board uses the LDS antenna by default. Follow HELTEC's GNSS IPEX diagram and hardware modification guidance before switching to an external GNSS antenna. What is included in the default package? The default package includes the Wireless Tracker V2 board, one spring LoRa antenna, one SH1.25 x 2 battery connector and two pin headers.
