Generic 42 Multi-Function 2.4GHz RF Wireless Module – Receiver test panels

Description

The 42 multi-function 2.4GHz RF module is a compact, ISM-band wireless transceiver engineered for command-response and no-response communication protocols. Its architecture supports both transparent serial data passthrough and direct digital switch control, providing flexibility for remote automation, telemetry, and device management systems. The module’s +3dBm transmit power and -95dBm receiver sensitivity deliver a reliable 100-meter range in open environments.

Power management is a core feature, with a typical idle current of just 20µA and a wide 1.8V to 3.6V operating voltage, making it suitable for coin-cell or Li-ion battery-powered endpoints. The integrated PCB antenna eliminates the need for external components, while the -40°C to +85°C industrial temperature rating ensures stable performance in demanding conditions. This module is a foundational building block for custom wireless control networks in smart home, medical device, and industrial IoT applications.
