Nope, I (painfully) read through the first thread and didn’t find what I was looking for. We could really use a “flag as inappropriate” button for some of the arguments there. It really seems like something that the NTC folks should have added to the pinout. The biggest problem there is that the max current sourcing on the VCC-3V3 pin varies because of XIO, Audio, and other circuits that already draw power from the same signal. Unfortunately, all we have is the schematic.
The last thing I would like to do is to pay for some custom PCB’s only to realize that CHIP can’t power them. I could send out for a separate power supply PCB (which I would do instead of an external power supply because it would need to be tested before added to the final cape), but that just unnecessarily wastes time and money on what is likely to be a mildly expensive project anyway. With the brownout issues that NTC has had with their own capes and CHIP’s USB port, I had hoped they would have discovered some solid numbers on how much power CHIP can source on each of the VCC pins before a brownout occurs.
