[Tested] WLED controller based on ESP01S

Interface specification

The input is designed to be a DC005 female socket, and you can use 5.5 2.1 or 5.5 2.5 internal positive and external negative DC5V input.

The output is directly adapted to the WS2812 interface. The middle contact is Data. You can choose to directly weld the cable or use a header (please use a header that meets the current requirements). The output is connected to MCU GPIO2, which is the default interface for WLED firmware.

MCU selects ESP01S (can also be adapted to ESP01). All pins that need to be pulled up have reserved resistor interfaces. When using ESP01S, they can be left vacant as appropriate.

Instructions

First, flash the WLED firmware for ESP01S, install the MCU, and connect the light strip to the DC interface. The first 30 lights on the light strip should be configured as orange. At this time, you can configure the controller according to the WLED documentation.

ESP01 uses 3.3v for power supply, and WS2812 requires 5V. Refer to the solution found on the Internet and connect a 1n4148 conversion level to the upper and lower ends of ESP01 (it is said that it can be used normally if 5V is directly supplied to ESP01)
