For projects requiring communication in the globally utilized 433 MHz band, we offer the E22-400M30S module. This imported transceiver is a straightforward choice for simple, low-cost deployments on this popular, but often crowded, frequency. While it provides a standard 1-watt of power, its operation is confined exclusively to the 433 MHz spectrum, making it vulnerable to the significant interference common on this band from other consumer devices. This module is an option for hobbyists or international users in regions where 433 MHz is standard, but it lacks the resilience needed for critical applications.
E22-400M30S
-
Single-Band Operation: Operates only on the 433 MHz ISM band, a frequency known for high levels of interference from other electronics.
-
Basic Data Transmission: Provides simple wireless data link capabilities for non-essential tasks.
-
Standard Power Output: Features a 1-watt (30 dBm) amplifier for conventional long-range transmission on its fixed frequency.
-
Imported Components: This product is manufactured in China and is therefore not recommended for secure industrial applications or for any use within the American defense supply chain.
-
No Cross-Band Capability: Incompatible with all other LoRa bands, preventing the creation of resilient, multi-frequency communication networks.
