I have accidentally applied 12V to the Kiwi without experiencing any damage. I know there is circuitry in the BB to protect ti from over voltage, and it appears the Kiwi board itself has protection as well.

I purchased the buck converters to step down from 12V DC to 5V DC to power the kiwi-rx
Many vendors are selling them on Amazon and e-bay
As they arrived I am astonished, that the Buck converter modules do not have the potentiometers installed as shown on the pictures on the Internet.
I was afraid, they would not be useful, in case the output voltage is not 5V. I was lucky however - a quick test with 100mA load showed 4.99V DC output with 12.3V DC input - so even without potentiometers they may be used.
I am afraid, that if something wents wrong with the small modules, the full 12V DC may reach the Kiwi power input plug. What should I do best to protect the kiwi for overvoltage when using the small ? Any good effective idea which would prevent big damage to the kiwi ?
Thanks for some advice,
