Waveshare SX1268 LoRa HAT for Raspberry UART is a 433MHz LoRa communication HAT designed for Raspberry Pi, Arduino, STM32, industrial sensors, smart home nodes, building automation, smart metering, and long-range data collection. It is built around the SX1268 and uses UART (TTL) communication, making it suitable for projects that need a simpler serial LoRa workflow instead of a full LoRaWAN stack. By using LoRa spread spectrum modulation, this board supports long-range communication up to 5km in ideal conditions, together with auto repeating, wake-on-radio, carrier sensing, encrypted communication, RSSI signal indication, and wireless parameter configuration. It is a strong fit for developers who need robust private LoRa links for embedded systems and field devices. Important: This product uses a private LoRa protocol and does not support LoRaWAN. For regional deployment, confirm that the 433MHz band is allowed for your target market before ordering or deploying. Features SX1268 433MHz LoRa HAT for long-range wireless serial communication. Standard Raspberry Pi 40PIN GPIO header for Raspberry Pi series boards. Onboard CP2102 USB to UART converter for serial debugging. UART control interface for hosts like Arduino and STM32. LoRa spread spectrum modulation with up to 84 available channels. Supports wake-on-radio, deep sleep, RSSI indication, LBT, and carrier sensing. Supports auto multi-level repeating for longer-distance communication. Supports fixed-point transmission, broadcast, and channel monitoring.

Packing List SX1268 433M LoRa HAT x1 USB type A plug to micro plug cable x1 433MHz antenna x1 Other Content Why this board is usefulThis board is designed for private long-range serial communication, which makes it easier to deploy than more complex networked LoRaWAN systems when you just need point-to-point, broadcast, or relay-style communication. Long-range and low-power combinationThe support for deep sleep, wake-on-radio, and auto relay makes it especially useful for field devices that need to transmit over longer distances while keeping power usage under control. Compatibility noteThis 433MHz model is generally aimed at regions where the 433MHz ISM band is allowed. Always confirm your local regulations before deployment, especially if you are building products for different countries. Resources Waveshare Wiki Demo Code Package Schematic PDF UART Interface Wiki Category FAQ Does this product support LoRaWAN? No. This product uses a private LoRa protocol and does not support LoRaWAN. What is it best used for? It is especially suitable for smart home, industrial sensors, smart metering, long-range telemetry, and Raspberry Pi / Arduino / STM32 UART LoRa projects. How far can it communicate? In ideal open-area conditions, the experimental range can reach up to 5km, though actual distance depends heavily on antenna, rate, interference, and installation environment. What is included in the package? The package includes SX1268 433M LoRa HAT, USB type A plug to micro plug cable, and 433MHz antenna.
