esp8266-01 vs esp8266-12F deep sleep

[randobi99]

I have a program running on a version -01 (8 pin header) that consumes <1mA in deep sleep but the -12F version consumes ~35mA running the same program, both programmed with Arduino IDE, and no LEDs are on.
Any ideas why that is the case?

The only difference between these is the flash chip used. Apart from that, it will also matter what stuff is connected to the ESP8266 GPIOs. ESP-01 has very few IOs available so you cannot load down the pins and draw current.
But in ESP-12 you can connect low impedance loads and increase current sink/source on the pins. So make sure your loads are sleeping/high impedance.
