Special Features
Enhanced Performance & Connectivity - The upgraded Heltec V4 based on the ESP32-S3R2 MCU and SX1262 LoRa chip, supporting Wi-Fi, Bluetooth and LoRa communication. It delivers significantly higher transmit power up to 28±1 dBm and adds dedicated SH1.25-2Pin solar panel and SH1.25-8Pin GNSS (GPS) interfaces, making it ideal for remote, off-grid applications
Superior Hardware Upgrades - This kit features 16MB Flash and 2MB PSRAM for advanced UI and complex system design. It maintains pin and form factor compatibility with the V3, allowing reuse of existing accessories. The board also includes a protected OLED screen and an integrated FPC 2.4G antenna within its casing, enhancing durability and RF performance for all your LoRa and Meshtastic devices projects
Low Power & Easy Deployment - Engineered for efficiency, the V4 dev board boasts ultra-low power consumption (<20 μA) and features an optimized battery management IC that supports 3.3~4.4V lithium battery and 4.7~6V solar input. These design along with plug-and-play interfaces, make setting up Meshtastic node, LoRaWAN or custom Meshcore networks straightforward, even for beginners
Diverse Applications & User Scenarios - Whether you're a hobbyist, developer, researcher, or part of a community network, this board is a versatile tool. It's perfect for building devices for smart cities, environmental monitoring, industrial sensors, asset tracking, and decentralized communication meshes. It is compatible with Arduino, PlatformIO, and MicroPython and highly adaptable for prototyping and complex projects
Complete Developer Kit & Strong Support - This is a component kit that provides everything to start developing. The package includes the main board, a LoRa antenna, header pins, and connectors. Combined with an active global community support, these resources transform the board into a powerful Meshtastic radio solutions, guaranteeing a smooth path from unboxing to deployment
