About this item

The WIFI Kit series from Heltec Automation is a high-performance and cost-effective development board designed for IoT and long-range wireless communication projects. Built around the powerful Lexin ESP32 chip, this board integrates a Tensilica LX6 dual-core processor running at up to 240 MHz, delivering a computing performance of up to 600 DMIPS. It features 520 KB SRAM, built-in Wi-Fi (802.11 b/g/n HT40), a full TCP/IP stack (LWIP), and dual-mode Bluetooth (Classic + BLE), making it ideal for a wide range of wireless applications. What sets this board apart is its integration of the SX1276 LoRa chip, which supports LoRa communication at 868/915 MHz frequencies. This allows for ultra-long-range transmission with a sensitivity of up to -139 dBm and a maximum power output of +20 dBm. Under ideal open-field conditions, the board is capable of transmitting data over distances of up to 2.8 km, making it perfect for remote sensing, telemetry, environmental monitoring, and other low-power wide-area network (LPWAN) applications. The board is also compact and breadboard-friendly, enabling quick prototyping and seamless integration into custom hardware. With rich features and long-distance capabilities, Heltec’s WiFi LoRa Kit is a powerful tool for developers working on next-gen IoT solutions.
