I’m looking forward to trying out the new ESP12-S – this one apparently has a better antenna – and by the look of the schematic (see page 15 – thanks Alexander) the resistors on reset, GPI))0,2 and 15 are already there.
That should simplify layout somewhat!
Hmm, board layout with 0.1 pins, 3v3 reg with decent heatsink area underneath, maybe 3 mosfets…
So this should work with existing layouts. I’ve kept back an IoTBEAR adaptor and ordered a couple of these from Ebay sub- £2 each.
