Recently I've bought two isolated probes (from mouser). After attaching them to the target I've discovered that both consumes approx. 500 uA (measures with fluke multimeter). But I'm also have older stlink/v2 isol which I used earlier, and it hasn't that consumption! (it consumes <1 uA).
So I'm not sure what should I do with newer probes - is it okay for newest probe design to consume 500 uA from the target, or should I return them to the distributor for replace/refund ?
I've tried to disconnect SWIM and RST lines, consumption drops by 50 uA (25 uA from each line), but the old one still has a total consumption x1000 lower :sad_but_relieved_face:
