Description
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 stick version 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 AMB4420 and AMB2520 provide pin-compatible modules for the
frequency ranges 433 MHz and 2.4 GHz. AMBER wireless also offers
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.
