Description

Why do we need Maker series products?

Summary

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.

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.
