The WeMos D1 Mini offers 4MB flash memory, 11GPIOs, and 1 ADC pin in a minimal and small setup. The community has developed a wide variety of shields for the D1 mini board, which allows you to build small and simple setups with almost no wiring required. You just need to stack ...

The board also fit nicely in the case (see picture). It can be mounted in a switchboard. By default, Relay 1 use GPIO16 with have a pullup resistor. This activates the relay at powerup. This can be changed to another GPIO with a small wire. I tested it using the onboard power...
ESP8266 12E Wemos D1 Mini pinout Wemos D1 Mini development board has a total 16 pins in which 12 pins are active, uses ESP-12 module, onboard reset button, 3.3 voltage regulator, Micro USB, USB to UART bridge and some other components. ...
This is a simple schematics to help connect items to the board, the pinout name is still valid for NodeMCU V0.9 and Wemos D1 mini, the "phototransistor" part can be completely omitted, continue reading if you wanna connect something of analogic to the ADC (A0 pin). ...
2 hours later, I've realised the IR hat I had on the D1 mini is the wrong way around 🤦 Worth double checking this peeps. musapinar commented Apr 24, 2022 For people coming via search engines: I had this issue when I was using long Dupont wires from the USB FTDI to the ESP....
BTW, I set up a D1 mini I had lying around, added a 1k MFR resistor (wire-wound and some cheap CFR significantly distorts the waveform, and shows about 0.5uH at 100kHz on my LCR meter) on pin D5 (DATA_PIN 14 in the code), and used an LED light strip I bought a few months...
