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.
