7 Hardware design
SPSGRFC module supports SPI hardware interfaces.
Notes
 All unused pins should be left floating; do not ground.
 All GND pins must be well grounded.
 The area around the module should be free of any ground planes, power planes, trace
routings, or metal for 6 mm from the module antenna position, in all directions.
 Traces should not be routed underneath the module.
7.1 Modules RF compliance limits
The RF compliance limits are those tested for FCC, IC and CE certification using the dedicated
dongle (PC92A.V01). These limits are enforced by the dongle firmware. Care must be taken with
custom application firmware to ensure these limits are not exceeded, voiding the FCC, IC and CE
certification.
