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.
● 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.

FAQ
A1: It does not support Meshtastick's screen display mode. 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.
A2: If you want to use the new ESP32-S3 processor and the SX1262 LoRa chip, you may need to use new libraries that support them. You should check that the libraries you are using are compatible with these new components.
As far as my experience with the Wireless Stick Lite is concerned, the only library I had to change when switching from V1 to V3 was the LoRa library. The Sandeep Mistry LoRa library that I used earlier doesn’t work with the new SX1262 LoRa chip. To make my code work with the V3, I had to migrate to the Heltec LoRaWan_APP library. This was a true migration because the two libraries don’t use identical calls.
A3: Due to the small screen of the board, it does not support Meshtastick’s screen display at present. You can download the firmware of the Wireless Stick Lite directly.
A4: Imagine that you want to measure the moisture in your field. Although, it is not far from your house, it probably doesn’t have Wi-Fi coverage. So, you can build a sensor node with an ESP32 and a moisture sensor, that sends the moisture readings once or twice a day to another ESP32 using LoRa.The later ESP32 has access to Wi-Fi, and it can run a web server that displays the moisture readings.This is just an example that illustrates how you can use the LoRa technology in your ESP32 projects.
