Open source hardware small project: anxinco esp-c3f control ws2812

---

Preface

        I believe you still remember , I sent one before ESP-C3F control WS2812 Project , In case everyone really forgets , Now let's recall ： Anxinco ESP32-C3 Module Alibaba cloud remote control WS2812RGB Light Bar （ be based on ESP-IDF Of SDK）.
        This project didn't show you the hardware part until the end , That's because bloggers don't want to Syria li Sub style wiring display , Satisfy everyone's curiosity , I took a picture ：

Debugging phase , It's so ugly , I didn't send it , Today is finally the end of debugging , Also changed , The effect is OK .

One 、 Software specifications

        The whole hardware is used Lichuang EDA pro Design , Lichuang EDA The professional edition is designed on the web , Therefore, you are required to keep your network normal .

        Some smart students said , Why don't you AltiumDesigner, Or some more professional design software is not good ？ The blogger's explanation is like this :
       1.AltiumDesigner Of course, it is easy to use , Bloggers are also using , But this project is completely open source , Of course, the design software used should also be genuine and free ;
       2. Lichuang EDA pro It is completely independently developed by China EDA Design platform , And some functions are AltiumDesigner Not available , For example, component array distribution ,PCB Component quick array layout , Very interesting , Support domestic .

Two 、 Schematic design

1. Lamp bead array

        Bloggers used 24 star WS282 Lamp beads , Each lamp bead has a decoupling capacitor , Prevent lamp beads from interfering with each other , The lamp beads are connected in parallel （ This arrangement of components can be automatically generated ）.

2.ESP-C3 Peripheral circuits

3、 ... and 、PCB Design

1. Component layout

Bloggers for convenience , Put the lights in a circular array , You can put out various shapes according to your own aesthetics .

2. 2D Preview

Four 、 Physical display

5、 ... and 、 Board instructions

1. connection

        Power input ：USB Interface
        Serial port debugging and download port ：TX Pick up USB To serial port module RXD,RX Connected to module TX,G Connected to module GND,V Mouth is there USB Access time , You can't answer it .

2. Program download instructions

        Make sure the wiring is correct :
       (1) USB There is power input ;
       (2) TX、RX and G Right access USB Serial port module .
        When the board is powered on , Hold on IO9 key , Then press the reset button , After releasing the reset key, the module can enter the download mode ：

Be careful ： Because the lamp beads are connected in parallel , So we can't realize the effect of running lantern for the time being ！！！！
