Heltec Wireless Stick Lite(V3) 902-928 Mhz
HTIT-WSL is a development board for Wi-Fi, Bluetooth and LoRa. Because some customers do not need OLED screen when using WiFi Lora32, Heltec launched this product.
The HTIT-WSL is composed of an MCU (ESP32-S3FN8) and Semtech LoRa Transceivers (SX1262), which perfectly support Arduino®. Users can easily carry out secondary development and application. This supports Arduino® and can run the LoRaWAN protocol stably.
Main Features
- LoRa band 902-928 Mhz
- 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;

Dev board return policy
Development boards are specialty items that generally cannot be resold on return, especially if the firmware has been flashed. Defective boards can be replaced or returned for refund within 30 days of purchase. Non-defective boards can be returned in the same time frame if in like-new condition with a 20 percent restocking fee applied. If the board has had altered firmware or became bricked due to a non-standard firmware flash, the board may not be eligible for return.
Sales tax is required in many states and will be added at checkout if applicable to your delivery state. Tax exempt forms can be sent to our support department.
