Please ensure your board enters Bootloader mode before flashing. Here’s how:

Connect the USB-C cable, then hold down the PRG button, press the RST button once, and release the

PRG button. After that, flash the firmware. Once the flashing is complete, remember to restart the device.

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, PlatformIO, 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.
