Ra-02 SX1278 LoRa 433MHz Wireless Transceiver Module for Arduino, ESP32, STM32 & Raspberry Pi

Ra-02 SX1278 LoRa 433MHz wireless transceiver module is a long-range RF communication board that adds LoRa 433MHz data links to DIY and embedded systems, making it ideal for remote sensors, telemetry, home automation, and robotics. Built around the SX1278 transceiver, it supports low-power, long-distance wireless networking over a standard SPI interface, so it can be integrated with Arduino, ESP32, STM32, and Raspberry Pi controllers. Use it to send and receive serial-style data between nodes, gateways, or custom IoT prototypes where reliable sub-GHz communication is needed.
