E22-400T22S LoRa Wireless Module certified with CE、FCC、REACH、ROHS

Introduction

In the global IoT market, wireless modules must not only deliver excellent performance, but also obtain the mandatory access certifications required by target markets. Certifications such as CE (EU), FCC (US), REACH (EU chemicals regulation), and RoHS (environmental) are the necessary "passports" for products to enter mainstream markets including Europe and North America.

The classic product E22-400T22S from Chengdu Ebyte Electronic Technology Co., Ltd. (EBYTE), with its CE, FCC, REACH, and RoHS four international certifications, has become a highly trusted LoRa wireless data transmission module. This article provides an in-depth analysis of the meaning of these certifications and how the E22-400T22S, with its outstanding product features, has become an ideal choice for global customers in long-range, low-power IoT applications.

CertificationNameRegulatory RegionCore Requirements
CEEU Mandatory Safety CertificationEuropean Economic Area (EEA)Product meets EU basic requirements for safety, health, and environment; mandatory for entering the European market
FCCUS Federal Communications Commission CertificationUnited StatesEnsures the product's electromagnetic radiation and interference immunity meet US standards; mandatory for entering the US market
REACHEU Regulation on Registration, Evaluation, Authorisation and Restriction of ChemicalsEURegulates the production and use of chemicals in the EU market, ensuring products meet environmental, health, and safety requirements; a comprehensive environmental compliance standard
RoHSRestriction of Hazardous Substances DirectiveEURestricts the content of six hazardous substances such as lead and mercury in electrical and electronic products; an important mark of environmental compliance

The fact that the E22-400T22S has obtained all four certifications simultaneously means it has met the access thresholds of the most stringent markets in the world, providing strong compliance assurance for customers' product exports.
