Brief Introduction
E30 series wireless transceiver modules, operating at 425-450.5MHz (default: 433MHz) are based on originally imported SI4438
from Silicon Labs, with transparent transmission available, TTL level, WOR (ultra-low power consumption). They feature half duplex and
two kinds of interface: SMD and DIP.
The module has the function of data encryption & compression. The data of the module transmitted over the air features
randomness. With the rigorous encryption & decryption, data interception becomes pointless. The function of data compression
decreases the transmission time & probability of being interfered, while improving the reliability & transmission efficiency.
E30 series strictly stick to the design rules home and abroad of FCC, CE, CCC and meet the related RF certifications and export
standards.
