$36.00
Description
Haltec V3
WiFi LoRa 32 V3, also called Heltec V3, durable IoT maker kit powered by the ESP32S3 MCU and SX1262 LoRa Node chips. Integrated three wireless communication ways —LoRa、BLE、and Wi-Fi， along with an on-board OLED display, it presents a robust, all-in-one solution.
Its superior RF design and stable, minimal system design ensure the product is ready-to-use “out of the box,” and support for development methods like Arduino, Platform IO, ESP-IDF, and MicroPython make it beginner-friendly.
It is now widely used in well-known long-range wireless open-source projects such as Meshtastic and Meshcore, serving applications in smart cities, smart farms, industrial control, and security systems.
