It would be nice if this had the middle two columns of holes added (the ones that are in the space between the left and right half of the breadboard). I often need adapters from double-row header pins (for connecting to IDC cables) to breadboard spacing. I understand why they don’t put it on plastic breadboards, but I don’t see a reason why it would be detrimental on one like this. A line of silkscreen down the middle should be enough to visually indicate where the middle is.

How much does one of these strips weigh?

Thanks Mike, I agree with your assessment. I’ll ask them just to make sure, since it seems like that is essentially indistinguishable from having no sleep mode at all.

The datasheet mentions putting it to sleep by disabling the power regulator. It’s not entirely clear to me whether they are suggesting that I add another 3.3v regulator and disable that one or whether they are suggesting that I pull down the REG_ENA (pin 36) signal.
Does anyone know whether pulling down pin 36 will sleep the Venus638flpx? If nobody knows I will try to cut traces on my breakout board and find out.

I’m confused. I see the firmware update file above, but nowhere in the documentation can I find how one is supposed to go about feeding this firmware upgrade to the chip.

Could you explain the role of capacitor C4?
I notice that there isn’t a capacitor there in the reference design included in the datasheet, but SparkFun added one.
I confess to not understanding the purpose of the inductor either. The datasheet reference design labels it “optional” but doesn’t explain why someone might choose to include or exclude it.
