Frequently asked questions

Is the XENSIV

™

BGT60TR13C radar wing compatible with other feather-compatible kits?

Yes, the XENSIV

™

BGT60TR13C radar wing can be used with any board that has a feather-compatible pin-

out.

Can we combine the XENSIV

™

BGT60TR13C radar wing with other boards, i.e. XENSIV

™

PAS CO

wing?

Yes, the XENSIV

™

PAS CO

wing and XENSIV

™

BGT60TR13C radar wing boards can be stacked together. It is

simple to combine the radar code example, i.e.

https://github.com/Infineon/mtb-example-sensors-radar-

presence-freertos

with the XENSIV

™

PAS CO

code example. Both examples use the FreeRTOS task, which

can be easily integrated into a single application.
