8 AC530 Application board for UC530
The Fastrax Application Board AC530 provides the UC530 connectivity to the Fastrax Evaluation Kit or to other
evaluation purposes. It provides a single PCB board equipped with the UC530 module, MCX antenna connector,
Antenna Bias +3.3 V switch, VDD Power Switch, switch for GPS_ON control and 2x20 pin Card Terminal connector.
Default host port configuration is set to UART by switch S4… S6 ‘ON’ and S7 & S8 ‘OFF’. S3 should be ‘ON’ for first
power up; for successive power up and for low power modes the S3 shall be switched to ‘OFF’.
8.1
The following signals are available at the 40-pin Card Terminal I/O connector J2. The same pin numbering applies
also to the Fastrax Evaluation Kit pin header J4. Note that UART Port 0 maps to serial Port 0 at the Fastrax
Evaluation Kit. I/O signal levels are CMOS 3.3V compatible unless stated otherwise.
