The AMB2220 is a compact high performance radio data transmission module for wireless half-duplex communication. The integrated microprocessor controls data communication, handling packet and checksum generation, addressing, monitoring of channel access and re-transmission of lost packets. The host system does not have to perform any radio-specific tasks. The embedded software protocol stack supports star and peer-to-peer networks.

The module can be configured in many ways and supports data transfer with fast channel and address switching. An opportunity to assess the quality of the radio link is also provided by using the measured field strength (RSSI value). The graphical user interface of the freely available Windows application “AMBER-ACC” makes it easy to set operating parameters.



The AMB2220 is connected to a host system via the UART interface with bit rates of up to 115.2 kbaud. Other pins are used for data flow control and to switch between operating modes. Using appropriate firmware, the module is also suitable for autonomously recording digital or analogue signals.

Range of Applications

Data collection, monitoring, remote control and sensor networks. Its compact dimensions and low power consumption make the radio module ideal for battery-powered devices.

Automatic Assembly

If ordered in tape & reel packaging, this module is suitable for automatic component placement.
