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.
US Purchase: Amazon.com <$30.00USD

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
