Docs & Resource
Summary
The WiFi LoRa 32 V4, the next gen to the Heltec V3, is a powerful, high-efficiency IoT maker board featuring an ESP32S3 MCU and SX1262 LoRa Node chip; retaining the V3's size and identical pinout, it integrates performance upgrades including a built-in Wi-Fi/Bluetooth antenna, 28±1dBm LoRa output power, and a protected OLED display; its superior RF and stable system design ensure it's ready-to-use and highly beginner-friendly, supporting development via Arduino, Platform IO, ESP-IDF, and MicroPython; making it ideal for long-range wireless open-source projects like Meshtastic, LoRaWAN, and Meshcore in applications such as smart cities and industrial control.
Base on ESP32-S3R2 & SX-1262, supports Wi-Fi b/g/n, BLE, and LoRa communication.
2MB PSRAM and 16MB external Flash, more suitable for UI and complex system .
High-power version with LoRa transmission power increased to 27±1dBm.
Form factor and pin compatibility with WiFi LoRa 32 V3.
PC casing protects the screen and integrates FPC 2.4G antenna.
Added SH1.25-2P solar panel interface.
Optimized lithium battery management.
