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), and RoHS (environmental) are the necessary "passports" for products to enter mainstream markets including Europe and North America.

The classic product E22-900M22S from Chengdu Ebyte Electronic Technology Co., Ltd. (EBYTE), with its complete certification combination of CE, FCC, and RoHS, has become a highly trusted 868/915MHz surface-mount LoRa™ wireless module. This article provides an in-depth analysis of the meaning of these certifications and how the E22-900M22S, with its "ultra-compact size, long-distance communication, and industrial-grade stability" features, has become an ideal choice for global customers in applications such as smart home, wireless metering, and scientific and medical use.

The fact that the E22-900M22S has obtained all three certifications simultaneously means it has met the access thresholds of the two core markets in the world, providing strong compliance assurance for customers' product exports.

Certification completeness: ★★★★ (Three certifications complete, accessible in the core European and North American markets)

In-Depth Analysis of Product Features

Obtaining global certifications is only one reflection of a product's capability. The E22-900M22S itself is equally impressive in its product design and technical parameters.

Core Solution: New-Generation LoRa Spread Spectrum Technology

• Core chip: Based on the original SX1262 RF chip from Semtech (USA). Compared with the previous-generation LoRa™ transceiver, anti-interference performance and communication distance have been further improved;

• LoRa spread spectrum technology: Adopts new-generation LoRa™ modulation technology, with anti-interference performance and communication distance far exceeding that of current FSK and GFSK modulation products.

Ultra-Compact Size and Long-Distance Communication Capability

• Ultra-compact size: The module measures only 14 × 20mm, adopting a surface-mount package (stamp hole/IPEX), ideal for space-constrained embedded applications;

• High transmit power: Maximum transmit power up to 22dBm (160mW), transmitting farther and more stably;

• Ideal communication distance: Under ideal conditions, the communication distance can reach 5.5–7km, meeting long-range IoT application needs.

Ultra-Wide Frequency Range

• Wide frequency coverage: Supports an ultra-wide applicable frequency range of 850–930MHz, backward compatible with SX1278 and SX1276, flexibly adapting to the band requirements of different countries and regions;

• Industrial-grade crystal oscillator: Uses an industrial-grade high-precision 32MHz crystal oscillator, ensuring reliable and stable wireless communication quality.

Industrial-Grade Standard Design

• Wide voltage supply: Supports 2.7–5.5V power supply, with optimal performance guaranteed above 5V;

• Industrial-grade temperature range: Supports long-term operation at -40 to +85°C, adapting to various harsh industrial environments;

• Multi-country certification assurance: RF performance and component selection follow industrial-grade standards, and international authoritative certification reports including FCC, CE, and RoHS have been obtained, so users need not worry about its performance.
