1. Overview

1.1 Introduction

E30-433T20S3 is a UART module based on Silicon Labs'
SI4438. It features half-duplex with transparent transmission,
SMD packing, TTL level output, WOR and 433MHz working
frequency. This product has been mass-produced and can be
used in a wide range of environments and industries.
The module has a software FEC forward error correction
algorithm, which has high coding efficiency and strong error
correction capability. In the case of sudden interference, it can
actively correct the interfered data packets, greatly improving
reliability and transmission distance. When without FEC, such
packets can only be discarded. The module has data encryption. Data transmitted over the air, with randomness, makes
data interception meaningless through strict encryption and decryption algorithms. The function of data compression
decreases the transmission time & probability of being interfered, while improving the reliability & transmission
efficiency.
E30-433T20S3 series strictly stick to the design rules home and abroad of FCC, CE, CCC and meet the related RF
certifications and export standards.
