What is a WeMos D1 Mini Tutorials? A WeMos D1 Mini is a small Wi-Fi-enabled board based on the ESP8266 chip. It has 18 digital input/output pins (of which 4 can be used as PWM outputs), a micro USB port, a power jack, an ICSP header and a reset button. The WeMos D1 Mini is a great way to get started with ESP8266 development.

Step 3: Wiring. 1) Cut half of the existing dupont cable, so it becomes around 10cm. 2) Connect female header on dupont cable with male header on LED Dot matrix panel, see picture. 3) Separate the cable into two parts, 2 cables for VCC & GND, 3 cables for CLK DS & DIN. then enter into the hole on the pcb, see picture.
