The ESP8266 specs are on the Espressif website. As for the motor, Google “dc 3v n20 micro speed gear motor stall current rating”. The no-load current may be within spec but the stall current (max load current) may be your issue. A simple motor driver circuit can be made with only 3 or 4 components if it becomes an issue.

I think a 500mA VReg will be OK if all you are powering is the Wemos D1 Mini and no other accessories. But to reduce the chance of power brownouts during random peak currents, I suggest adding a 330uF to 470uF 10V low ESR electrolytic directly on the D1 mini's 5V power pin. Short leads to 5V and Gnd (installed on D1 Mini not the PSU).
I am trying to interface Wemos D1 Mini to Atmega16 and have communication between them using TX and RX pins.According to the datasheet, the maximum allowed current for the Wemos mini is 3.3V for all IO pins while the Atmega 16 is giving 5V at it's IO terminals.For this problem, I could come up with just one solution and that is to use a voltage

Let's look at the IRLZ44N, the threshold voltage is 1-2V, so it will turn on with 3.3V. The value of R DS on was your concern, we have this as given for V GS =4V, R DS = 0.035Ω, sinking 21A. Lets just take this as a starting point, assume the values would stay the same at 7A, so you're burning 7 7 0.035 = 1.715 W in the transistor.
[WeMos D1 Mini back by Tpkull via Wikimedia Commons, CC BY-SA 4.0.] In my last article, I went over how I was able to program the WeMos D1 Mini ESP8266 development board via the Arduino IDE. Though there a few hoops to jump through — including making sure your cable works — once it is set up, it’s pretty easy to get it to do Arduino-ish
So, if you want to use a Wemos D1 Mini with these led strands just make sure that you ignore the arrows and wiring common sense and send your signals into socket end of the strand. The really good news is that you can probably connect the Wemos directly to the led strand. My leds work without my carefully assembled level converter.
This should do what you want. Basically this is looking at the board from the bottom so the pins are all swapped left to right. WeMos-D1-Mini-reversed-pins.fzpz (18.4 KB) Peter. GRenken May 14, 2022, 4:29pm 5. This part worked just fine. Thank you Peter. I am working on a sketch that uses a Wemos ESP8266 ESP-12F D1 Mini microprocessor. The pin
A delay() puts the WiFi of the WeMos AFAIK to sleep for some random time (about a second and a bit IIRC). So use millis() to manage time between analogReads, not delay(). Can also use a single resistor (not a voltage divider) between sensor output and analogue input, because the WeMos D1 mini already has a voltage divider buildin.
The 5 V capacitor will suppress interference from the PWM affecting the LED commands, The regulator will generally be able to manage the bursts of RF transmission. The WeMOS D1 Mini is supposed to be complete and adequate as is, it is the LED strip that is the additional component. ShermanP December 31, 2019, 3:39pm 9.
