Brief Introduction

E30-400M30S（4438） is a hardware module (SPI) based on the SI4438 RF chip imported from Silicon Labs. It is a half-duplex, SMD integrated transceiver with transparent transmission available. With working frequency band 425 ～ 525MHz, transmitting power 1w, it is suitable for a variety of environments. The original imported SI4438 RF chip from Silicon Labs(USA) features high receiving sensitivity and strong anti-interference, supporting the development of low power consumption as well. It has been widely used in various industries and has the characteristics of stable performance, long transmission distance, and strong ability of penetration and diffraction, etc.
