ESP32 LoRa V4 Development Board + L76 GNSS Module, Upgraded ESP32-S3 SX1262 LoRa WiFi Bluetooth 2MB PSRAM 16MB Flash 915MHz Antennas OLED Display Supports GPS & Solar for Arduino Meshtastic LoRaWAN

About this item

  • Integrated High-Performance GNSS + LoRa for Precision Tracking: Now featuring the advanced L76 GNSS module with multi-system support (GPS, GLONASS, QZSS, SBAS) and EASY/AlwaysLocate technologies for ultra-fast cold start (<15 sec) and low-power operation (~2.6mA). Combined with upgraded ESP32-S3R2 and SX1262 LoRa chip, this ESP32 development board delivers reliable real-time location data for asset tracking, smart agriculture, and outdoor IoT deployments—ideal for engineers and makers building GPS-enabled wireless sensor networks.
  • Enhanced Processing Power & Memory for Complex Applications: Powered by ESP32-S3 with 2MB PSRAM and 16MB Flash, it handles complex firmware, UI rendering, and multitasking effortlessly. The high LoRa transmission power (28dBm) and sensitivity (-137dBm) ensure long-range communication, while seamless integration with the L76 GNSS enables precise geolocation logging—perfect for industrial monitoring, environmental sensing, or mobile LoRaWAN nodes.
  • Full Expansion & Outdoor Readiness with Solar & GNSS Support: Expand functionality easily with dedicated SH1.25-8Pin GNSS interface and SH1.25-2P solar panel input (4.4-6V). Perfect for outdoor Meshtastic GPS trackers, solar-powered sensor networks, or off-grid environmental monitoring. Combine with a 915MHz LoRa antenna for maximum coverage.
  • Ultra-Low Power Design with Smart Power Management: Optimized for low-power applications, sleep mode draws less than 20μA. Battery management features support lithium battery charging, overcharge protection, and seamless switching between USB and battery/solar power. It is an ideal solution for portable or remote deployments like wireless alarms, water meter reading, or mobile LoRaWAN nodes.
  • Plug-and-Play Compatibility for Rapid Prototyping: Backward compatible with ESP32 LoRa V3/V2 pinouts. Fully supports Arduino IDE, MicroPython, and ESP-IDF. Features USB Type-C with ESD protection, dual IP EX antennas (LoRa + 2.4GHz), 0.96” OLED display, and expanded headers. A top-tier development platform for IoT creators and Meshtastic users needing an all-in-one solution with built-in GPS, WiFi, Bluetooth, and LoRa connectivity.
  • Note: 1.The screw securing the upper left corner of the screen is a specially customized plastic screw, distinct from the other three screws. Its purpose is to avoid interfering with the 2.4GHz radio frequency and is not defective. 2.Flash the firmware first before use, otherwise the screen will be blank. The stable version of the system does not have V4 firmware, you can use 2.7.11 or 2.7.12.
