nRF52833 DK Addon Antenna Array

[wvfan]

Hi,

I'm now planning to test BLE AoA using nRF52833 DK. For now the DK doesn't have antenna array, so I plan to use an addon board like below:

Is there any link or example that can tell me how to connect the addon board to DK ( for RF signal ), at which PIN and use which type of connector? Thanks.

Hi,

 

The connector on the DK is a MM8130-2600, you can use MXHS83QE3000 with that which also has SMA in the other end. 

 

Best regards,

Andreas

Hi Andreas,

I would like to know which pin should we connect to?

Is there any example for nRF52833 connect to GPIO configuration for AOA antenna?

Thanks

Best regards,

Hi Joanne,

 

You need to configure these pins in the PSEL.DFEGPIO[n] registers. We do not have an example unfortunately, but it is illustrated in this whitepaper: https://infocenter.nordicsemi.com/topic/nwp_036/WP/nwp_036/intro.html?cp=16_0

 

Best regards,

Andreas
