The Pico +ESP8285 board uses about 110mA at 5V. That's a lot more than the Raspberry Pi Pico W, which functions well on around 40mA. I've found that it is possible to put the ESP8285 into deep sleep mode, using the 'AT+GSLP=<time>' command. That reduces the current consumed by the module to around 40mA - which about matches the PicoW, showing the superiority of the official design in this regard. I also found that the ESP firmware provided for the module doesn't support a time-out, but at least that means you can still use the module as a standard Pico board with Wi-Fi and Bluetooth communications disabled, with a much lower current drain for battery operated projects, etc. I found that 'AT+GSLP=1' is all that is needed.
It may be possible to build your own ESP8285 firmware too, per: https://wiki.sipeed.com/soft/maixpy/en/ ... mware.html but unless there's some specific use case which favours the ESP8285, why do it?
