Wireless Tracker (Heltec and MakerFocus)

Please note that this github is for Version 1.1 of the Heltec/Makerfocus Wireless Tracker. All new boards sold are version 1.1.

The Wireless Tracker is a cutting-edge development kit that combines the power of ESP32-S3FN8, SX1262, and UC6580 chips. This trifecta of hardware enables the device to provide versatile IoT applications, from GNSS solutions to LoRa communications plus an onboard OLED display. Whether you're tracking assets, monitoring livestock, locating vehicles, or safeguarding children, the Wireless Tracker is the perfect fit.

Features

Advanced Chips

ESP32-S3FN8

Connectivity: The ESP32-S3FN8 supports both Wi-Fi and Bluetooth connectivity, allowing for versatile wireless communication.
GPIO Pins: There are 11 GPIO pins available for various functions-the rest of the ESP32 pins are used for various connections to other chips:
- 4 (GPIO, ADC1_CH3)
- 5 (GPIO, ADC1_CH4)
- 6 (GPIO, ADC1_CH5)
- 7 (GPIO, ADC1_CH6)
- 15 (GPIO, ADC2_CH4, U0RTS, XTAL_32K P)
- 16 (GPIO, ADC2_CH5, U0CTS, XTAL_32K N)
- 17 (GPIO, ADC2_CH6, U1TXD)
- 26 (GPIO, SPICS1)
- 37 (GPIO, SPIDQS, FSPIQ, SUBSPIQ)
- 45 (GPIO)
- 46 (GPIO)
- 47 (GPIO) and 48 (GPIO) do not seem to influence the GPS in any way, even though they are connected to Boot_Mode (could put GPS into firmware upgrade mode) and D_SEL (which could remap internal GPS pinout). They appear to be free of use to the user.

--Note-- The pinouts below are for version 1.0, Heltec has not provided a version 1.1 for us to reference. You can view the full V1.1 Schematic here: Heltec Wireless Tracker Schematic FYI- 0.5 = V1.1 and 0.3 = V1.0

ESP32-S3FN8 Pinout

SX1262

LoRa Communication: The SX1262 module facilitates long-range (LoRa) communication. LoRa is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology, allowing for long-range communication with low power consumption.

UC6580

GNSS Solutions: The UC6580 module provides fast Global Navigation Satellite System (GNSS) solutions. This allows for high-precision tracking, making it suitable for applications where precise location tracking is crucial.

Advanced GNSS Capabilities

Dual-frequency multi-system based on 22nm technology.
Supports L1 + L5/L2 positioning.
Compatible with multiple satellite systems: GPS, GLONASS, BDS, Galileo, NAVIC, and QZSS.

Design and Interfaces

Type-C USB Interface: Equipped with voltage regulation, ESD protection, short circuit protection, RF shielding, and more.
Battery Management: Onboard SH1.25-2 battery interface with integrated lithium battery management system, including charge/discharge management, overcharge protection, battery power detection, and automatic switching between USB and battery power.
Connectivity: Dedicated 2.4GHz metal spring antenna for Wi-Fi and Bluetooth. Reserved IPEX (U.FL) interface for LoRa and GNSS.
Display: 0.96-inch 160x80 dot matrix OLED for showcasing debugging information, battery status, and more.

Power Metrics

Power Consumption:

UC6580 uses 45 mA through Vext
Tracker uses 35 mA @ 80 MHz (Vext disabled)
Tracker uses 18.5 uA during deepsleep, if done properly

Developer-Friendly

Seamless compatibility with the Arduino development environment, simplifying innovation and prototyping.

Applications

Bicycle Sharing: Track bicycles in real-time.
Pet and Livestock Tracking: Ensure their safety and monitor movements.
Vehicle Location: Manage fleet vehicles or locate personal cars.
Child Safety: Actively track and ensure children's safety.
