Looks like a more modern Gerrit

🪦

Oh this looks nice, is there somewhere one can follow this?

A DSL which outputs kicad netlists would be a fun little project

Parts could have their requirements, e.g. surrounding passives, differential pairs, length matching, current reoriented, ... encoded. And linters & CI could check that it's followed or a known "accept the risk of not following". I think the answer is "it's how it's always been done"

Sure one would want to sometimes view things, but that sounds like something that can be generated. And eventually one would trust the type system more and more.

Yeah the SPI interfacing ones are around 4 euros, though if you have a MAC the RMII ones are in the 2-3 euro range. :)

If you want to try something fun, I can recommend power over datalines (PoDL) using single pair Ethernet (SPE). It's easy to integrate as well if you use the 10MBit standard, there are SPI based transceivers. So you can either get multi drop (T1S) or long cables (T1L).

When adding pads for external use like you have done, I really like protection parts which have built in current limiting and ESD protection. Quite versatile, easy to solder :D www.onsemi.com/pdf/datashee...

Isn't there one from wch? www.wch-ic.com/products/CH3...

Is it's consumer grade IMU that is not clocked via an clock reference input then you can expect +/- 3-5% over temperature in my experience. If you need accurate sampling times, eg when doing inertial odometry, always timestamp on the MCU :)

It's just a bit unfortunate that ASCON uses 64 bit words for its operations which optimize badly on 32 bit ARM, so it does not beat ChaCha20Poly1305 on Cortex M :( still a very nice cipher github.com/korken89/asc...
