We are developing an IoT device that utilizes the nRF9151. We would like a review in the second round of our schematic and layout to understand if there is any issue that may cause troubles in our prototype rev01.
Attached you can find schematic, gerbers, stack-up / impedance calculation, and a print showing the part of the layout we would like Nordic to take a look.
The rest of the layout is not done yet. So, please pay attention only to the Nordic portion on the top of the layout.
This board is our second round. The first board rev00 didn't work. We were using another part number of nRF9151 before and there is another ticket (340088) open to talk about Firmware issues in that board.
Now, we are jumping to a second round of prototypes rev01, and we will use the part number NRF9151-LACA-R.
