Hi,
I'm reworking my PCB to upgrade from the 2040 to the 2350.
The recommended PCB footprint has me a little concerned though - I just wanted to double check.
I see it's packing in an extra 4 pins into the same outline as the 2040, but the result is that the corner pads have 0.1mm vertical and 0.1mm horizontal clearance (0.141mm diagonal). It just seems a little tight, considering the pads are otherwise 0.2mm clearance.
So I get why it's like that, just wondering if the pads could be nudged outwards a tiny bit to get the clearance back up. Suppose it's not a big deal, it just means I have to select the box for a tighter clearance when getting boards manufactured.
