Heltec HTIT-WSL SX1276 wireless stick lite 868-915Mhz development board with antenna compatible.

Wireless stick lite

Many users need a version without OLED display, because they want to use it directly in their IoT projects as the main controller
and RF (LoRa, Wi-Fi, BLE) connection. Compare with Wireless Stick, “Wireless Stick Lite” has much better low power design (30uA in
deep sleep). Removed the 0.49″ OLED, use ESP32-PICO MCU (it’s more friendly for low power design).

 Upgraded Version IOT Development Kit SX1276+ESP32 Chip Full support for standard lorawan protocol.

                               

Full Support for Arduino IDE

The product can be programmed with standard library and concise development language to quickly complete the scheme verification and product development

The Arduino example of the esp32 + lorawan protocol is provided

Direct Chip Level Development

The product does not use popular WiFi / Lora and other modules, but makes special modulation in function according to the needs of its own product, which can better match the needs of the product itself

Three Wireless Communication Protocols

Esp32 chip, supports WiFi / ble4.2/lora wireless communication function

WiFi Speed

150Mbps

LoRa Maximum Output Power

18dB ± 2dB


Receiver Sensitivity

-128dBm


Shield Cover: Strong Anti-interference

The shielding cover is installed on the module, which greatly improves its anti-interference ability

Upgraded Version, Smaller and More Energy-saving

Integrate the advantages of traditional wireless modules, reduce the product size and energy consumption

Only 5cm in length and 2.5cm in width

All kinds of Intelligent Scenes are Applicable

It can be used not only as a gateway of Internet of things products, but also as a driving terminal product
