Full Expansion & Outdoor Readiness with
Solar & GNSS Support: Expand functionality easily with dedicated SH 1.25 -8Pin GNSS interface and SH 1.25 -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.
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 + 2.4GH z), 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 2.4GH z 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.
