Hi,
The product's market has no limitations on the frequency band, which means we could use either 6843 or 1843. The PCB design is 6843 oriented and almost done, but IWR6843 is still in the preview status. Before moving to the next step, we have to make a decision on which one is the best option for the moment.
The questions are:
1. Are those two products are pin-to-pin compatible?
2. What differences do we have to consider except the antenna performance and the geometry pattern?
3. Which one do you suggest to choose?
Cheers
Tom
