Heltec LoRa ESP32 Wireless Stick Lite(V3) ESP32-S3 SX1262 Wi-Fi+BT Development Board 433MHz 868MHz 915MHz LoRa Kit for Arduino Meshtastic IoT LoRaWAN

Summary:

HTIT-WSL is a development board for Wi-Fi, Blue-tooth and LoRa. Because some customers do not need OLED screen when using WiFi Lora32, we launched this product.

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, Blue-tooth three network connections, onboard Wi-Fi, Blue-tooth dedicated 2.4GHz metal spring antenna, reserved I-PX (U.FL) interface for LoRa

- Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing.

- Support the Arduino development environment;

- Support meshtastic;

- 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;
