Hi,
I'm working on a four layer PCB including the nRF7002 for WiFi location finding. After looking at the various Altium Design files available (Thingy91X, nRF7002Dk, nRF7002EK), I'm a little unclear on the options available for the design of the isolated ground plane around pins 25 to 34. Your DK and Thingy91X have these tied with blind vias to the ground layer on layer 2, whereas the EK uses conventional through vias across all four layers. Please could you indicate how critical this aspect is, since at the moment, this is the only section that would require blind vias and hence would add significant cost to the board.
Many thanks in advance.
Andy
