Description: The WiFi LoRa 32 V4, the next generation of the Heltec V3, is a powerful and high-efficiency IoT development board. It features an ESP32-S3 MCU and an SX1262 LoRa chip, retaining the V3's size and pinout. The board integrates performance upgrades including a built-in Wi-Fi/Bluetooth antenna, 28 1 dBm LoRa output power, and a protected OLED display. Its superior RF performance and stable system design ensure it is ready to use and highly beginner-friendly. It supports development via Arduino, PlatformIO, ESP-IDF, and MicroPython, making it ideal for long-range wireless open-source projects such as Meshtastic, LoRaWAN, and Meshcore, in applications including smart cities and industrial control.
