Is there a pinout for the J1 connector for the micorhard add on?

We have the airbone innovations picoradio module and the radio chip is soldered in place.  
Wondering if we can make an adaptor cable to use this radio on our FlightStack?

The VOXL B2B connector pin-out can be found [here](https://docs.modalai.com/voxl-datasheets-connectors/#j13-expansion-b2b-connection)

It sounds like you may be more interested in the stand-alone Microhard dongle? https://www.modalai.com/products/mh-sa

Thanks,
I missed that going through the documentation.
We would prefer to use the direct add on but what we already purchased is

We also need to incorporate FIPS 140.2 validated radios.  
Currently microhard does not have FIPS 140.2 Validated radios and Doodle labs in in process.   Doodle labs is borderline for us on throughput for our application.  So we need to see about integrating different radios which could require a adaptor cable.
