I've got five esp-07/12 breakout boards, but the ESP-12 modules to go with them never arrived (aliexpress is pretty shady!) but it seems the ESP-07 variant with 16 pins including ADC (instead of 14) and external/ceramic antennas actually work out better than ESP-12's with chip antenna's?
Alternatively, the ESP-201's look pretty good, how do they compare with number of usable GPIO's - seems they are external and chip antennas, and of course don't need a breakout for breadboarding.
Is there a new favourite these days?
