Great explanation and side-by-side comparison with common-use examples, it couldn't be better. In my case, I was looking at using an Arduino UNO ready-made shield on the Wemos D1 R32 ESP32 and hunted everywhere for a physical, functionality and code difference comparison that I would have to account for. This video answers all my questions, thank you.

Your instructions are always clear for newbies like myself, thank you.

so clear and very usefull . Thank you

Sehr gut, hatte einige Probleme mit dem Arduino UNO D1 RS32 - konnte alle lösen.

Great explanation. Thanks for educating us.

I bought 4 boards of ESP32 D1 R32 from different suppliers to test. All have different print label so I assume they probably are made from different factories. Output voltage of 4.3-4.6 volt at 5 Volt pin is somehow intentional by design. I found that the 5V pin on the board has to be left alone and the board will work fine. If you feed 5V supply voltage to 5V pin, the board will not work and WiFi will be unpredictable and serial port will have problem. If you draw current from 5V pin to drive load such as LED or buzzer, the board will be unpredictable too. The board is often freezed if I mess around with this 5V pin. At first I thought the board is malfunction but it cannot be the same for all. If you leave this 5V pin untouched, the board will work well as charm. Do not worry about 4.3-4.6 volt that you can measure from this 5V pin. Leave it alone and it will work very well. It took me a while to find out this. If I need 5V to feed my load, I add a separate cheap LM7805 to give my 5V load and sensor. Power 9-12 Volt adapter to the board 2 ways either via the 2.5 mm Jack or Vin PIN. I love this form factor as it is complete in itself. I do not have to buy the base. Just mount besides breadboard. I can even use simple wire I cut myself at any length without using Dupont pair wire because the board connectors are all female type. Lastly, it is cheaper than other form factors on AliExpress. Only do you have to know the trick of 5V pin. I think they should remove this pin so it do not confuse people. I cannot explain the reason for this finding because I do not have schematic of this board. I guess it may have to do with RS232 chip but I do know for sure. If anyone know the answer why, please share with all of us. ESP32 Wemos D1 R32

Thanks for the video. Got a question, is there any way to know the pin numbers? I bought this board, but as of now, fail to get its schematics.

Make video about connecting 3.5 tft display with this esp32 wemos d1 r32

What is the analog input pin?

Tks! Great Video!

I seen a simple servo motor project using a Wemos D1 R2. Will the ESP-32 you have shown in the video, be able to work on that? I'm not 100% I can transfer everything over as I'm kind of a newb. If not, what is the next best thing to the Wemos D1 R2? Thanks

Can I use this wemos d1 Arduino as a nrf24l01 to wireless cominication.

is the GPIO pins of Wemos ESP-32 D1 is same as arduino UNO , i want to buy my first IoT board but which board shall i buy arduino r3 or Wemos D1 ?

Have you tried any of the UNO shields? I have used the ESP32 before and the pins were not all TTL compatible (3.3V rather than 6V)

If plug in DC JACK 12v. vcc output will be 12v. as well?

Hi,can you please tell me to use this esp 32 board in arduino ide which board we have to select in the arduino ide .as the name of this board "esp 32 wemos D1 R32" is not present in the arduino ide .

Hello, Is WeMos board compatible with the uno shields?

trying to find GRBL for the Wemos D1 R32 UNO

can i use cnc shield in wemos esp32?

this is a wonderful video... can you tether an esp32-camera module ttl-serial-com to a ttl-uno and using the usb-uno port for programing? thanks..:) arduino-girls should tune in here..:)

So, you don`t put them one on top of the other, they are not connected like a 3.5 raspberry touch screen

hey i was trying to upload a simple hello sketch but i am getting this any idea how to resolve this esptool.py v3.0-dev Serial port /dev/cu.usbserial-1410 Connecting..... Chip is ESP32-D0WDQ6 (revision 1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 9c:9c:1f:e3:8f:80 Uploading stub... Running stub... Stub running... Changing baud rate to 921600 Changed. Configuring flash size... A fatal error occurred: Timed out waiting for packet header A fatal error occurred: Timed out waiting for packet header

Please help. It does not work

:( very intimidating. I tried ordering from Ali express and even messed that up! But found a esp32 more analogous to the nano than the uno

Recently [6/xx/23] got 4 of these and the WiFi totally sucks -- no range
