    Known good esp-atlas asserts this board↔firmware link at the shown trust tier — it does not guarantee your specific unit or the current firmware version. Flashing can erase keys/config and can brick the device. At your own risk.

Notes

  • ESP32-S3FN8
  • SX1262 LoRa transceiver; UC6580 L1+L2/L5 dual-frequency GNSS module
  • Separate IPEX (U.FL) antenna interfaces for LoRa and GNSS
  • ESP32-S3FN8 ordering code is 8 MB in-package flash with no PSRAM, per Espressif's ESP32-S3 series datasheet
  • io.gpio_exposed=28 QUOTED: Heltec's Wireless Tracker datasheet Pin Definition table lists Header J2 GPIO {44,43,36,35,34,33,47,48,26,21,20,19,0} (13 pins) and Header J3 GPIO {37,46,45,42,41,40,39,38,1,2,3,4,5,6,7} (15 pins) -- 28 header-exposed pads total, the same carrier layout as the sibling V3 boards; the SX1262's SPI bus (GPIO8-11) and RST/DIO1/BUSY (GPIO12-14) are wired off-header directly to the radio
  • io.gpio_free=11 DERIVED: subtracting esp32-s3's soc.reserved_pins that are exposed here (strapping {0,3,45,46}: all 4 present; usb_flash_tied {19,20,35,36,37}: all 5 present -- 9 total), then the onboard ST7735S TFT and UC6580 GNSS pins per meshtastic's heltec_wireless_tracker variant.h -- TFT (CS=38, DC=40, MOSI=42, SCK=41, RESET=39, backlight=21: 6 new pins) and GNSS (RX=33, TX=34, RESET=35, PPS=36; RESET/PPS are already removed via reserved_pins, so 2 new: 33,34) -- gives 28 - 9 - 6 - 2 = 11
