Excuse the high price. it's a pain to assemble by hand and i don't have a stencil yet.

This is the dact pico. If you take a ruggeduino and smash it together with a pi pico, you get something like this. With overvoltage, overcurrent and i guess some static discharge protection on every IO, i feel like you wouldn't break this without actively trying. Along with that it has a switching voltage regulator which can accept up to 32 volts without issue and provide 700mA constant and 2A burst as it's currently set up. The power input also passes by multiple ferrite beads and capacitors to clean it up, and multiple polyfuses, diodes and TVS diodes to stop the worst from happening. There is one fuse on the main power input, another on the USB power input and a third near the IC to stop too much current being pulled through it. The analog voltage reference has a LM4040 to get rid of any potential noise there.

Except for that it's basically a normal pi pico. Though it also has USB-C and a reset button for your convenience.
