AMB8425 Compact Low-Cost Radio Module 868 MHz SRD Band Key Features Low-cost OEM radio module in 868 MHz SRD band Compact dimensions: 16 x 27.5 x 3.5 mm Supports low-power applications and WOR (wake-on radio) Integrated software stack with extensive functions Flexible addressing with up to 255 nodes in 255 networks Complies with requirements in R&TTE Directive 1999/5/EC Tape & Reel packaging for automatic component placement Also available as wireless USB adapter (AMB8465) Network Topologies Description The AMB8425 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) Point-to-point 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 AMB8425 to a PC system. The AMB8425 is constructed on an SMD design. If delivered in tape and reel packaging, the module is suitable for automatic component placement. Interfaces The AMB8425 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 Point-to-Multipoint 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.
