I have booted a compile of -13.5 on them, as well as a -current (as of 
perhaps 6 months ago -- not so "current").

I've used SPI-interfaced peripherals (accelerometer/gyro), I2C 
(pressure/temperature sensors), and serial ports (BT-LE chips) on these 
rugged little beasties.

Most of my use cases do not require anything with a beefy CPU, as 
they're mostly data collection units with nice onboard tools and ssh 
access.

They seem to last a lot longer than the RPi Zero 2W's that I've tried 
using. The Broadcom chip, or the RPi system design, seems very sensitive 
to the least little bit of ESD or having an I/O pin shorted to ground. 
Those chips really were meant for the inside of a cell phone and not to 
have unprotected I/O brought out to a user header. Also, I don't have to 
add an external dongle for wired Ethernet.

(Also, what less-than-stellar engineer thought up putting the 5V and 
3.3V rails right next to each other on the expansion header without 
putting GND in-between them? One slip of a probe tip and poof, there 
goes your RPi.)
