Step 4: Select Board and Port. Connect your nodemcu mini. Select port where Nodemcu is connected. select board as Wemos D1 R1.
I connect gnd>gnd, 5v>5v and d1>d1 - nothing works with relay blink code. I change connection to d5 on wemos (still d1 on relay) and it works fine with code change to d5. Any ideas, as at present I can't stack the relay on the wemos? (because the d1 goes to d1) According to pinout, D1 is "I/O, in the default mode, SCL of I2C" and GPIO5. Thanks
It features a USB Type C charging module and a lithium 3.7v battery. The Wemos D1 Mini does nothing but send a mqtt message when it wakes up through the touch button and an phototransistor by grounding the RST pin. Thanks to one user’s help on the board, I managed to achieve this by programming the Wemos D1 Mini. I would like the Wemos
WeMos D1 mini Pro . Contents. WeMos D1 mini Pro. Hardware. Configuration. Uploading. Debugging. Frameworks. Hardware . Platform Espressif 8266: ESP8266 is a cost-effective and highly integrated Wi-Fi MCU with built-in TCP/IP networking software for IoT applications.
The WeMos D1 is an ESP8266 WiFi based board that uses the Arduino layout with an operating voltage of 3.3V. the board is controlled by the ESP8266 chip (a 32-Bit processor) and has a larger flash memory compared to an Arduino Uno. It consists of 11 digital I/O pins and 1 analog (input) pin. the board can be connected using a Micro-B type USB cable.
Wemos D1 mini ATX power switch in action. Super. Now you just pull out the LED, and connect the D1 via a resistor to the ATX power switch pin that has the 3V pullup. If you like your power switch to work as well, you can wire the POWER SW jumper cable to breadboard, and from the to the motherboard, and just connect D1 to the same pin.
