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.

Bulk/High Value Order Returns

Due to the labor required to package and ship bulk orders, as well as cost and stock issues involved in replenishing items, bulk orders of 5 pieces or more are not returnable unless the equipment is defective or mis-advertised, or a return period is prenegotiated. For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.


Items on backorder or preorder will ship as estimated on the item page. You can cancel an order any time up until shipment. Orders with expedited shipping will arrive in the advertised time after the order ships, not after the order is placed.
