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

• Upgraded ESP32-S3 & SX1262 Core for High-Performance IoT Projects: Powered by the advanced ESP32-S3R2 and SX1262 LoRa chip, this ESP32 development board delivers robust WiFi, Bluetooth LE 5.0, and long-range LoRa communication. Ideal for Meshtastic nodes and Arduino-based wireless projects requiring reliable connectivity and real-time data transmission in smart agriculture, industrial monitoring, or remote sensing.
• Enhanced Power & Memory: Experience superior signal strength with up to 28dBm LoRa transmission power and ultra-low reception sensitivity (-137dBm). Equipped with 2MB PSRAM and 16MB Flash, it excels in running complex firmware, UI interfaces, and multitasking applications—perfect for ESP32 dev boards used in IoT devices, asset tracking, and home automation systems.
• Full Expansion 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.
• Long Battery Life + Smart Power Management with Solar Input: 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. Now equipped with a 3000mAh rechargeable lithium battery, enabling extended operation in portable or remote deployments such as wireless alarms, water meter reading, mobile LoRaWAN nodes, and off-grid sensing solutions—ideal for uninterrupted field use.
• Plug-and-Play Design: Backward compatible with ESP32 LoRa V3/V2 pinouts and fully supports Arduino IDE, MicroPython, and ESP-IDF. Features a 0.96” OLED display, USB Type-C with ESD protection, dual IP EX antennas (LoRa & 2.4GHz), and expanded header pins. A top-tier choice 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.
