Thanks for reading!
Yeah, custom hardware is something I want to do more of, but I have a hard time with it since I'm not much of a hardware guy, so I stick to the Pi. It's a pain in some ways, but it has the big benefit of a large user base so there's a lot of support.
I've been working on the custom PoE HAT for a few months, and the last two months has just been running in circles trying to find ICs in stock. The EE consultants I'm working with say this this would normally be something we could build easily for $20/unit, but with the chip shortage, everything's out of stock. I've even okayed them to look for parts that would drive it up to $50/unit just for the HAT, but we're still not finding anything.
My plan is to do the custom hardware in baby steps, like start with the custom PoE HAT, then see if I can integrate the TC358743 into my HAT for HDMI capture, then maybe move to Pi CM4, then maybe something even more custom.
- cushychicken 5y agoThat seems like a sensible design progression - it lets you slowly chip away at the parts you don't need. The IC shortage is driving everyone in hardware bonkers at the moment, myself included. I wish I had better input for you here, except that we're in it together for at least the next six to twelve months!
- jpm_sd 5y agoAlso an eastern MA EE here - shortages now are the worst I've ever seen (20 years into my career). It's a brutal time to be introducing a new product. I'm having to spin new board revs just to use whatever chips I can currently scrounge from brokers. Suppliers are telling me they can see the light at the end of the tunnel, but it's looking like mid/late 2022.
