Heltec Automation Heltec Wireless Stick Lite V3 with ESP32-S3FN8 and SX1262 Type-C USB LoRa Development Board 433MHz 863-870MHz 902-928MHz Support Bluetooth WiFi and LoRa Connections (902-928MHz)

Powerful ESP32-S3 & LoRa Performance: Powered by the ESP32-S3FN8 dual-core processor (up to 240MHz) and SX1262 LoRa chip, supporting Wi-Fi 802.11 b/g/n ( 2.4GH z), Bluetooth 5.0, and long-range LoRa communication. Delivers up to 21dBm transmit power and -134dBm receiving sensitivity for stable, long-distance IoT connectivity. ^^ Compact Stick Form Factor & Convenient Interfaces: Featuring an ultra-slim stick design ( 58.0822. 68.2 mm) with breadboard-friendly pin headers, its ideal for portable and space-constrained projects. The reversible USB-C port supports fast programming, power delivery, and battery charging, while an onboard SH 1.25 -2 battery interface enables direct lithium battery integration with overcharge/discharge protection. ^^
Ample Memory & Versatile I/O: Equipped with 8MB quad-SPI flash, 512KB SRAM, and 384KB ROM, it provides sufficient storage for complex IoT applications. It offers 45 programmable GPIOs, plus multiple interfaces, making it easy to connect sensors, actuators, and custom peripherals for diverse use cases. ^^
Wide Compatibility & Easy Development: Fully compatible with Arduino, ESP-IDF, Meshtastic, and LoRaWAN protocols, it supports rapid prototyping and commercial deployment. Heltec provides pre-configured libraries, open-source examples, and detailed documentation, lowering the barrier to entry for hobbyists, engineers, and IoT developers. ^^
Robust Build & Reliable Performance: Designed with industrial-grade components and circuit protection (ESD, over-voltage, short-circuit), it operates reliably in temperatures ranging from -20C to 70C. The included SMA antenna and RF shielding ensure strong signal stability, making it suitable for harsh outdoor and industrial environments.
