Maxcio W-DE004

Contributed based on work by Michael Harwerth from Germany

Quite affordable (4-pack for 47€ on Amazon) Wifi Plugs. Of course, they have their own mobile phone app, but that's not what we're looking for, isn't it?

Introduction

• Input voltage: AC100-240V 50/60Hz
• Working Current: 10A
• Has power meter: NO
• Power consuming: ≤0.3W
• Dimensions L2.96 x W1.57 x H0.98"
• Has a USB port which alledgedly outputs 2.1A (it's also used for supplying power when flashing)

Flashing

Drill a hole in the botom cover. This will allow you to easily pry off the cover

Loosen the two screws that are now exposed and you now have access to the insides

USB Port connector is a good place for connecting GND

RX, TX and GPIO0 are marked here

For flashing, connect up RX<->TX and TX<->RX as usual to your programmer, GND to GND and hold GPIO0 against ground, then power it up via the USB port. Possibly there may be a way to connect 3.3V directly. I don't know, need to get myself a new multimeter one of these days and check it out.

Pinout

Here is the pinout for the WiFi module
