Breakout boards / Re: ATX Breakout Suggestion
Hi Ian I couldn't find specs for the V2, but from what i see from the Kicad screenshot you are going to add VADJ, are you going to use lm317/lm337?, there will be current measurement points or a micro to do that?

If I may, i would suggest to replace the lm317 with a LT3083 or LT1083, and instead of using a potentiometer(assuming that is what your going to use) use a digital potentiometer. Why all this?, the LTx083 will let you shutdown the Vadj output just shorting to ground the ADJ pin. So if we also are able to measure the current(i'm assuming that a current sense resistor will be there) we can drive the LDO and have CC and CV using an external micro to drive all.
Otherwise you could add and leave unpopulated a low pass filter +opamp to ADJ pin so if someone want can drive the LDO using an external micro.
