Heltec V4 ESP32 LoRa 32 SX1262 OLED Development Board Meshtastic Kit

Built-in OLED Display for Instant Data Insight

• Monitor your project's vital signs without any extra hardware. The integrated 0.96-inch OLED display (128x64 resolution) provides a crisp, clear window into your system's operation in real-time.

• View sensor readings, network status, GPS coordinates, or debug messages instantly. This built-in screen transforms the board from a simple module into a complete LoRa Meshtastic kit, ready for immediate prototyping and deployment.

Built for the Elements - Robust Power & Protection

27dBm High Power Transmission for Unmatched LoRa Range

• Push the boundaries of wireless communication. Our V4 development board boasts a massive 27±1dBm transmit power and an exceptional -137dBm receiving sensitivity. This means you can build Meshtastic devices and LoRa radio networks that reach farther and connect more reliably than ever before. We have also included the enhanced-signal GT-800 antenna, which features a gain of 4dBi.

• Whether you're covering a smart farm, a large industrial facility, or an urban neighborhood, our board ensures your data packets get through, making it the ultimate solution for long-range, low-power applications.

Advanced Solar Charging & Ultra-Low Power Management

• Designed for 24/7 outdoor and off-grid operation. We've revolutionized the power management system, featuring an ultra-low deep sleep current of less than 20μA for years of battery life.

• The dedicated solar panel interface allows you to harness the sun's energy, creating self-sustaining Meshtastic solar nodes for permanent outdoor installations. The optimized lithium battery management ensures safe and efficient charging, making it perfect for asset tracking and remote monitoring.

Ready for Precision Navigation - Connect to the World

GNSS Port for GPS Connectivity & Accurate Tracking

• Add precise geolocation to your IoT devices with ease. The V4 introduces a dedicated SH1.25-8P GNSS interface, designed for plug-and-play connectivity with external GPS modules.

• This critical feature enables high-accuracy asset tracking, vehicle monitoring, and any application requiring exact location data. Build sophisticated Meshtastic GPS nodes that don't just communicate but also know exactly where they are.
