Version 2 WeMos Mini

The new Wemos Mini (V2) is now available on AliExpress as confirmed in the forum post at

Reported to be easier to flash and 30% increase in radiating area.

Good to see the AE listing now states the correct (3.2V) maximum analogue port input rather than their earlier incorrect listings for version 1 that stated 3.3V. Pinout for version 1 still wrongly states 3.3V though.

Maybe one day they will bring out a V3 which will accept 3.3V i.e. the operating voltage of the device itself.

We have found most ESP’s to be VERY tolerant when it comes to power ratings and many will tolerate much higher voltages than their published rating, but not if you are working with analogue readings.
