Description

Why do we need Maker series products?

Summary

● In order to meet the user’s requirements for high performance and small size, we designed this product. On the basis of WiFi LoRa 32, it’s has a smaller size, 0.49″ OLED display, and better RF characteristics.

● 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.

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 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.

● 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.

Wireless Stick (V3) supports the following development methods:

Compared to Wireless Stick (V2), V3 has made the following upgrades:

Wireless Stick is compatible with the following open-source projects:

● ESP32 Paxcounter

● Disaster Radio

● Meshtastic

● Tiny GS

● ...

We also provide a standard ESP32 Arduino LoRaWAN library:

● Heltec ESP32 LoRaWAN

This library is already included in the Heltec ESP32 Arduino Framework by default.
