      I'm apparently hard on these modules?

      There have been a couple of 4-Relay modules (U097) that I have found where the relay sticks off. We was able to find a drop-in replacement (TE T77S1D3-05), but still don't know why the original relays were sticking (I did a tear-down analysis, but haven't gotten authorization to send it through the x-ray machine yet).

      Now I have had two DAC2 modules (U012-B) fail. On one the boost just ... isn't switching anymore: 4.88V at the output (what you'd expect after a single diode drop). The other is still under analysis, but there is no boost output and the IC gets hot

      All this to say: is there a place where the Bill of Materials for M5 stuff is accessible? The schematics and some datasheets are available at https://docs.m5stack.com/. However, the schematic is often lacking relevant part specifications or part numbers.

      At the least it would be useful to figure out WHY the modules are giving up the ghost (am I demanding too much output current? Do I need to layer additional protections?). Being able to replace parts may sometimes be helpful too.
