Infrared+MQTT,ESP32C3+PWM brushless small ceiling fan

My current hardware conditions are: install a docker container in Synology NAS (Snail Star), install Home Assistant in the container, and install MQTT integration in HA;

In fact, this fan can be run independently (infrared remote control), and MQTT is convenient for operation and remote control on the mobile phone; I have just played with HA, and I will change the 86 box to connect to HA in the future;
if it suits the electrical devices I have + I draw the schematic diagram of the PCB board by myself. Anyway, it’s mainly just a few wires. I’m an online porter and a novice on the program!
I share the PCB and schematic diagram on "EDA Open Source Hardware Platform" and search for: infrared + MQTT, ESP32C3 + PWM brushless small ceiling fan, (still under review, you may see it in a few hours, and the schematic diagram is also attached)
Let’s briefly introduce the functions and functions of this controller:
1) The fan adopts PWM stepless speed regulation. The speed is adjusted to a suitable speed, suitable for sleeping. It also adds simple simulation of wind from outside (4S~8S random time changes and plus or minus 16 PWM Changes)
2) Connect to HA, you can operate it on your mobile phone, such as preset modes: low, medium, high, natural wind, power on and off, display temperature, humidity, power supply voltage, see the short video for details, it is very cool; At the same time, the infrared remote control also controls all functions;
3) Save the speed before power outage; if the network is disconnected during use (lost MQTT connection), you can also connect yourself (connect yourself 5 times) and the connection is not functional and you can run off the network;
4) Yes OTA wirelessly downloads the firmware. For detailed IP, please refer to the information sent by the serial port immediately after startup, generally such as: 192.168.**.***/update

In order to get the fan blade seat, I purchased a breeze electric fan from this company (I used an old fan that I had on hand, other companies may not be able to install it this way. If you have an old fan, you can try it): https://detail. tmall.com/item.htm?id=641443686991&spm=a1z09.2.0.0.53f32e8doNGE1I&_u=r284nul44bb

01--This is a 12.3 yuan motor.

01A--Infrared remote control (can be purchased from the same company as the motor)

1--PCB (the modification may be slightly different, please refer to the file)

2--PCB (the modification may be slightly different, please refer to the file)

3--PCB (the modification may be slightly different, please refer to the file)

4--Short the wires according to this picture, and the fan will reverse

5--Click to get this fan casing, you can only dismantle the old fan

6--Just for the seat to install the fan blade, cut it as shown in the picture.

7--Remove the unnecessary magnet again

8--Finally got the external fan blade seat

9--Press the hammer on the motor again and hammer it down. Rest assured that the size is just right.

10--Install the PCB and motor, that’s it, OK

11--Put a big nut on the screw to install it properly

12--Low current

14--Finally, you need to set up your own home WiFi network account to use the MQTT function. See the attachment for the configuration.yaml configuration.
