And finally, the Wemos dies! The final battery voltage, as measured by the Wemos A/D, was about 2.81V, after a further 3 days. This is a lot lowerr than the 3.2V stated in the Wemos data sheet. In total, with interruptions, the battery lasted about 336 hours, or 14 days, far longer than originally predicted! The Wemos D1 mini is ideal as it can be powered using 5V DC, the same voltage that will power the WS2812b LED strip. You can easily swap out the Wemos D1 mini with a NodeMCU as this micro-controller also accepts 5V input voltage. Another (cheaper) alternative is the popular ESP-01 module. I've had a good look through here and tried all the solutions but haven't had any luck, what I have is about 90 leds in a strip WS2811 12v, I'm using a single 12v psu for the job, into a regulator that's giving me the 5v for the D1/MCU, connected up D4 to the data pins with a 470ohm resistor and the strip to 12V, made sure its a common ground Wemos D1 Mini; TP4056 module with “discharge protection”, most modules with more than one chip has this, but be careful! Lithium-Ion battery, e.g. a 18650 cell, and probably a holder for the battery; What you don’t want is anything resembling a power bank or battery shield with a regulated output (5V or 3V). These are practically useless You have to save \"18 Generic\" first and when you go there again after the reboot you get the long table where you can change all the pin's parameters. These steps are confirmed to also work with the Wemos D1 mini PRO v2.0.0. Link to Wemos hardware & documentation .
