Frequently Asked Questions

What is the power supply requirement for the CHAFON MU922 module?

The MU922 module requires a DC power supply between 4.0V and 5.5V. It is designed to operate with standard 5V logic systems commonly found in microcontrollers, single-board computers, and industrial controllers.

What communication interfaces does this RFID module support?

The module supports two serial communication interfaces: a TTL-level UART (3.3V/5V logic compatible) and a standard RS232 interface. This dual-interface design provides flexibility for integration with modern microcontrollers (via TTL) or legacy industrial PCs and PLCs (via RS232).

Can I connect an external antenna to the MU922 module?

Yes. In addition to the integrated 3 dBi antenna, the module features an MMCX female connector port. This allows you to connect an external UHF RFID antenna if a different radiation pattern, gain, or physical placement is required for your specific application.

How do I adjust the RF output power of the module?

The RF output power, adjustable from 0 to 20 dBm, is configured via software commands sent over the serial interface (UART/RS232). This allows you to optimize the read range for your environment and ensure compliance with local regulatory limits on RF transmission power.

What is the typical reading distance achievable with this module?

Using the built-in 3 dBi antenna, the module can read standard UHF RFID tags at distances up to 100 cm (1 meter) under ideal conditions. The actual read range can vary based on the specific tag used, environmental interference, and the configured RF output power level.
