Here we are going to make a matrix LED 32x64 RGB. This is a connected screen, it is possible to connect at it easly by web pages and Get request. For this i use a Wemos d1 mini pro. I use a outdoor panel, it is water proof, it have also a great luminosity. The screen connected use a Wemos D1 mini pro like main processor, it is a ESP 8266 with 16 M. At this add a power of 5 volts 4 A to powered it. It is possible to update it trough web connection with bin file. It is set to be able to display three messages with two modes. It is possible to change color and to adjust luminosity.
The drawings and the codes are available on Github account. https://github.com/InnoGreenTech/Wifi_Screen_LED_64x32 .

1-How to set WIFI: When you connect the screen, it will tray to connect on wireless network. But it will not be able to do it, then it will open a portal that allow to set it. The name of of this portal is InnoGreenTech, you need to connect on it , use the password innogreentech. After you will able to open a setting page at the address http://192.168.4.1. After to set information, the screen restart and display the ip address, you can access at it by this address.

2-How it works: With your explorer at its adresse http://xxx.xxx.xxx.xxx . The main page is display. There are four areas : The menue to navigate between each pages.information area with date and hour; the message setting zone et the writing area. The area of configuration allow to activate the messages use. It possible to adjust the delay of display and the luminosity of messages. if luminosity is adjust at 0, the message is black.
The zone of writing allow to create messages. There are two modes, a scroll mode and a fixe mode. For each line it is possible to change the color. The first step is to choice the message with the form on the top. - In scroll mode only the line 3 is use, the string will scroll on the middle of the screen. -In fixe mode, the both first lines are fixed and automatically center. The third is a scroll line, if the string is to long.

4-Drawing and PCB:
I have made the drawing with Kicad software.
This is a PCB double face.

3-Assembly: There are four holes on PCB to fixe it on the power supply. A flat cable allow to connect the screen at the PCB, it is generally sent with the matrix LED RGB. It is really important to connect the ground of the power, it is for your safe.
