I'm looking to design a PCB that'll be carrying 40A peak (probably closer to 30A continuous) at 36V for my hauler project. Does anyone have any good guides on high current PCB design? Thinking in terms of recommendations on via stitching etc between polygons.

Realistically all the board will be doing is current monitoring with a couple of TI parts and a micro on a CAN bus, holding a fat relay as the battery cutoff, fuses and some connectors for power distribution.

DisplayPort is better than HDMI, and I will die on this hill

any tips on microphones / preamps for field recording very quiet outdoor environments?

my Zoom H4n (from 2008 or so?) seems to have quite a high noise floor (after digital amplification in Audacity) when the rec level is set to maximum and the environment is almost silent.

what are people using these days?

the H4n has a 3.5mm socket marked EXT MIC on the back, but I've never used it, and there are two line-level (afaik?) inputs (combined 1/4" jack/xlr sockets) on the bottom that I've used to record mixing desk and room audio simultaneously for live gigs (no complaints for that use case).
