MikroElektronika Communication & Wireless Development Tool, GPIO Interface, 433MHz MICRF230 Model

MikroElektronika MICRF230 Communication & Wireless Development Tool, model MIKROE-2902, is a wireless receiver designed for low-speed wireless ad hoc networks operating at 433MHz. It is engineered for use in remote control applications including fans, lights, garage or gate doors, and remote keyless systems.

The device features an ASK/OOK demodulator which enables amplitude shift keying and on-off keying modulation detection, combined with an analogue RSSI output for accurate received signal strength indication. It also incorporates an integrated squelch circuit to minimize background noise, enhancing the signal clarity.

The MICRF230 supports GPIO interface communication and can be powered by either 3.3V or 5V input, providing compatibility with a variety of systems. The module includes an embedded PCB antenna for standard range, while also allowing connection of an external antenna via an on-board SMA connector to extend communication distance and improve signal reception.

This wireless development tool complies with environmental and safety standards such as RoHS, WEE, and CE. Its certifications extend to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007, ensuring high reliability and adherence to quality protocols.

Applications for the MICRF230 include unidirectional, low data rate wireless links widely used in industrial, commercial, and residential automation, such as controlling garage or gate doors, toggling remote fans or lighting systems, and secure remote keyless access.

This device operates at a maximum frequency of 433MHz, suitable for low data rate wireless communications. Interface type is general purpose input/output (GPIO), facilitating easy integration. The module supports receive modulation duty cycles ranging between 20% and 80%.

It is designed as a Pb-free component, conforming to environmental standards. The product is manufactured in Serbia, affirming quality and origin transparency. Set contains one communication and wireless development tool with documented technical support.
