A few days ago I received four P2.5 126x64 RGB LED matrix ordered from AliExpress. In this blog, I will connect four LED Matrixes to create a 256X 128-sized display. Preparations are as follows. Materials Raspberry Pi 4 : 1 P2.5 128X64 RGB LED Matrix : 4 Electrodragon RGB LED Matrix HAT :1 Hub74 cable : 4 LED Power cable:2 5V power supply : 1 <P2.5 128X64 4EA RGB LED Matrix> <hub75 cable    LED power cable  5V Power supply> RGB LED Matrix HAT setup The 126X64 size RGB LED Matrix is ​​mostly 1/32 multiplexed. Be sure to check the manual of the LED matrix you use for exact details. If you're in 1/32 multiplexing mode, you'll need to tweak some of the Electrodragon HAT's jumper settings. <Electrodragon HAT jumper settings for 1/32 multiplexing> And I'm going to use 2 Hub74 sockets at the same time. Therefore, I will connect the HUB 74 sockets P1, P2 of Electro Dragon HAT together to the LED matrix. <Electrodragon HAT HUB 74 socket P1, P2 are connected
