The AMB8420 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 unreceived 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 quality of the radio link. The GUI for the freely available Windows application AMBER-ACC makes it easy to set operating parameters. A USB adapter is available to easily connect the AMB8420 to a PC system. The AMB8420 is constructed on an SMD design and suitable for automatic component mounting. It can also be delivered in tape and reel packaging.

The AMB2520 provides pin-compatible modules for the 2.4 GHz frequency range. AMBER wireless also provides design-in services as well as customer-specific solutions based on the AMB8420.

Interfaces
The AMB8420 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. An SPI interface is included. Using appropriate firmware, the module is also suitable for autonomously recording digital or analogue signals.

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