2 Set ESP32 LoRa V4 Development Board + 3000mAh Battery, Upgraded ESP32-S3 SX1262 LoRa WiFi Bluetooth 2MB PSRAM 16MB Flash 915MHz Antenna OLED Support GPS Solar A rduino Meshtastic LoRaWAN

High-performance IoT development board powered by the advanced ESP32-S3R2 and SX1262 LoRa chip, delivering robust WiFi, Bluetooth LE 5.0, and long-range LoRa communication. Excellent for Meshtastic nodes and Arduino-based wireless projects requiring reliable connectivity and real-time data transmission in smart agriculture, industrial monitoring, or remote sensing. Experience superior signal strength with up to 28dBm LoRa transmission power and ultra-low reception sensitivity (-137dBm). Fitted with 2MB PSRAM and 16MB Flash, it handles complex firmware, UI interfaces, and multitasking applications effectivelysuitable for IoT devices, asset tracking, and home automation systems. Expand functionality conveniently with a dedicated SH1.25-8Pin GNSS interface and SH1.25-2P solar panel input (4.4-6V). Great for outdoor Meshtastic GPS trackers, solar-powered sensor networks, or off-grid environmental monitoring. Pair with a 915MHz LoRa antenna for optimal coverage. Optimized for low-power applications, sleep mode consumes less than 20A. Battery management features include lithium battery charging, overcharge protection, and smooth switching between USB and battery/solar power. Includes a 3000mAh rechargeable lithium battery, enabling prolonged operation in portable or remote deployments such as wireless alarms, water meter reading, mobile LoRaWAN nodes, and off-grid sensing solutionsperfect for continuous field use. Backward compatible with ESP32 LoRa V3/V2 pinouts and fully supports Arduino IDE, MicroPython, and ESP-IDF. Contains a 0.96 OLED display, USB Type-C with ESD protection, dual IP EX antennas (LoRa & 2.4GHz), and expanded header pins. A premier selection among ESP32 boards for makers, engineers, and Meshtastic users. 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
