Why do we need Maker series products?
Summary
HTIT-WSL(Heltec Wireless Stick Lite v3) is a development board for Wi-Fi, Bluetooth and LoRa.
Because some customers do not need OLED screen when using WiFi Lora32, we launched this
product.It belongs to Heltec's LoRa ESP32 series.
The HTIT-WSL 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 240MHz).
SX1262 LoRa node chip.
Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF
shielding, and other protection.
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.
Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging
information printing.
Support the Arduino development environment.
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.

FAQ
Is wireless stick V3 compatible with V2 code?
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.
How can LoRa be useful in your home automation projects?
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.
