The AMB2720 is a compact and low-cost radio data transmission module for
wireless half-duplex communication. The integrated microprocessor controls
data communication, packet handling and checksum generation, addressing,
monitoring of channel access and packet re-transmission. 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 graphical user interface of the freely available Windows application
“AMBER-ACC” makes it easy to set non-volatile operating parameters.
The AMB2720 is designed as a SMT device and is suitable for automatic
component mounting. It can also be delivered in tape and reel packaging.
The AMB2730 provides a compatible alternative with increased radio range.
AMBER wireless also offers customer-specific solutions based on the
AMB2720.
 
Interfaces
The AMB2720 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. An SPI interface is also 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.
