Wireless Transmission Module with UART Interface and Spring Antenna
Wireless Transmission Module with UART Interface and Spring Antenna
Wireless Module is a high-performance, long-range transceiver based on the Semtech SX1278 LoRa chip, designed for ultra-long-distance, low-power, and low-data-rate wireless communication. Operating in the 433MHz ISM band, this module uses LoRa (Long Range) spread spectrum technology, enabling communication over distances of up to 10 km in open areas with minimal power consumption.
Equipped with a UART serial interface, the RA-01 is ideal for microcontroller-based systems such as Arduino, ESP32, STM32, and other embedded platforms. The included spring antenna enhances signal reception while maintaining a compact form factor suitable for space-constrained projects.
