Robot Radio 12V, Increased Brownout Risk?

[seg9585]

Yes of course, but I didn't realize the VRM can maintain 12V if it's input voltage was lower than 12V?
It's a regulator, is it also a transformer??

Transformers only work for AC, and FRC control systems run on DC. However, you're essentially correct in that the VRM functions as a bi-directional level shifter in order to provide a constant 12V supply.

I think it is a kind of "Boost Buck Converter" that steps up or steps down the DC voltage as needed.

They're a cool piece of tech.

We used the new Robot Radio on 'Snow Problem. We did not encounter any brownout issues, just a few setup issues.

We used the new radio on Team Cockamamie with no setup or brownout issues.

Operation is completely transparent after the setup issues?

We've had some interesting connection problems, however I'm not entirely convinced it's on the radio's end (quick fix involves taking down the wireless card on the laptop). Our radio also is not from a KOP, so we ended up having to follow these instructions to update it manually. It's possible that the firmware which shipped on the radio in the KOP and the firmware listed in that file are different.
