Re: ESP Power consumption & sleep mode

Dave Jones at EEV blog has some excellent videos about it - and he makes the micro-current so he should know!
I have one of his devices and using it I get a current consumption of 13.3mA using the node.dsleep() from the ESPlorer tool. However this is using the only module I have to hand with RST and GPIO16 broken out - a ESP-07 with 16 pins.
The power led must be accounting for lots of that figure, it's a bright blue one, and I don't really want to de-solder it at the moment.
Good work to track the power usage though - very important to work out how to maximise it otherwise people will be spending all their time changing/charging the batteries!
