I am developing a Boron LTE device that uses external power and I wanted to know if there is a Off The Shelf product that exists to block the external power from back feeding to my computer when I am doing debugging. Suppliers like Particle, Sparkfun, Adafruit or Tindie
@rickkas7 showed a version he made by hand in an earlier thread https://community.particle.io/t/power-to-boron-xenon/47661
I was curious if people have found versions of something like this that is avaliable for purchase. It seems like lots of folks will have this need to power up externally and use USB for debugging purposes.
