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.
Ultra-Low Power Design with Smart Power Management: Optimized for low-power applications, sleep mode draws less than 20A. 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 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.
