Wurth Electronics' AMB4426 is a compact and low-cost radio data transmission module for wireless half-duplex communication. The integrated microprocessor controls data communication, handling packet and checksum formation, addressing, monitoring of channel access, and resending not-received packets. The host system does not have to perform any radio-specific tasks.

The module can be configured in many ways and supports data transfer with fast channel and address switching. Measured field strength (RSSI value) offers the option of enhancing the quality of the radio link. The graphical user interface (GUI) for the freely available Windows application AMBER-ACC makes it easy to set operating parameters.

Interface

The AMB4426 is connected to a host system via the UART interface with bit rates of up to 115.2 kBaud. Other pins can be used for data flow control and to switch between operating modes. Using appropriate firmware, the module is also suitable for autonomously recording digital or analog signals.
