SPECIFICATIONS

Wireless Stick is a part of the “Heltec LoRa“ series, with the following features:

CE Certificate;

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

SX1262 LoRa node chip;

Micro 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 3D antenna, reserved IPEX (U.FL) interface for LoRa use;

Onboard 0.49-inch 64*32 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.

This is a standard LoRaWAN protocol that can communicate with any gateway/base station running the LoRaWAN protocol (requires serial number activation, only the development of the company) The board is available;

With good RF circuit design and basic low-power design (sleep current ≤800uA), it is convenient for IoT application vendors to quickly verify solutions and deploy applications.

1. Description:

1.1 Overview
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.
The V3 version is upgraded as follows：

Wireless Stick Lite are available in two product variants:
