Brand Name: Heltec Automation

Origin: Mainland China

Model Number: HT-WST V3

Product Information:


HTIT-WS is a development board for Wi-Fi, Bluetooth and LoRa. Its functions are basically the same as “WiFi Lora 32”, except that the screen is reduced to 0.49 inch and a shielding shell is added.
The HTIT-WS is composed up of an MCU (
ESP32-S3FN8) and Semtech LoRa Transceivers (SX1262), perfectly support Arduino®. Users can easily carry out secondary development and application.



Docs & Resource

We provide a comprehensive set of standard LoRaWAN libraries for our products.



Main Features:


  • Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual core processor, five stage pipeline rack Structure, main frequency up to 240 MHz).

  • SX1262 LoRa node chip.

  • Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.

  • Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching).

  • Integrated WiFi, LoRa, Bluetooth three network connections, onboard Wi-Fi, Bluetooth dedicated 2.4GHz metal spring antenna, reserved IPEX (U.FL) interface for LoRa use.

  • Onboard 0.49-inch 128*64 dot matrix OLED display, which can be used to display debugging information, battery power, and other information.

  • Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing.

  • Support the Arduino development environment.

  • We provide ESP32 + LoRaWAN protocol Arduino® library, this is a standard LoRaWAN protocol that can communicate with any LoRa gateway running the LoRaWAN protocol. In order to make this code running, a unique license is needed.

  • With good RF circuit design and low-power design.
