:D
Quoting my original message "The analogue inputs are designed to handle
shorts against a 12 Volt supply", that doesn't say 220V does it?
And IIRC single phase in the US is only 110-120V :b

Does it go to 220V? I mean if it is to be found people will try
to connect it!
LOL - nor to mention xxKv of static, etc!

With the current shortage and future price increase, it may
be worth investing in BeagleBone protection again ;-)
This 'surge protector' cape you mention already exists!
Shameless plug:
Have a look at the BeBoPr series of boards and the current
BeBoPr++. The analogue inputs are designed to handle shorts
against a 12 Volt supply. Besides the over voltage protection
you also get an extra (better) ADC, protected digital inputs,
both TTL and high current outputs, a 12-24 Volt to 5 Volt
step down converter, I2C level shifter, etc. Oh, and you can
also use it to control some stepper motors, e.g. to build a
3D printer, or a laser cutter, or a router, or something I
haven't thought of yet. There's a picture and manual
available for download via this link:
