Heltec LoRa 32 V4 LoRa Development Board

The Heltec WiFi LoRa 32 V4 is a high-performance IoT development board built around the ESP32-S3R2 dual-core processor and SX1262 LoRa transceiver.

Quality ESP32 S3 board integrates Wi-Fi, Bluetooth 5 (LE & Mesh), and long-range LoRa communication into a compact, low-power platform designed for next-generation IoT and Meshtastic applications.

With enhanced processing capability, optimized power management, solar input support, and GNSS interface expansion, this board is ideal for developers building scalable wireless sensor networks, outdoor tracking systems, and industrial IoT solutions.

Up to 28 dBm transmission power (high-power version). Deep sleep consumption below 20μA. USB Type-C, lithium battery, and solar input power supply methods support.

Kindly Note

This is the WiFi LoRa 32 V4 standard version. V4 is compatible with most V3 applications, but some LoRa transmission parameters may require adjustment due to upgraded RF performance.
