The microcontroller SERIAL-ports (1-3) are separately brought out, through which data can be transmitted to the controller. The DMD-STM32 Shield has a free area with contacts, on which additional elements or sensors can be mounted. ![]() You can use one of two interfaces ( SPI1 or SPI2) to control the LED panels. The DMD-STM32 Shield provides places for installing a 3.3V-5.5V 74LCX245WMX bidirectional level converter chip to control the LED matrix. Note: P10 LED panels work fine with 3.3V logic levels, but do not use a long ribbon cable to connect the DMD-STM32 Shield to the panel (<15 cm). The microcontroller is powered from 3.3 V, therefore the board is equipped with an AMS1117 voltage converter (5V to 3.3V). ![]() ![]() Why did you make it?Ĭontrolling LED panels requires a lot of microcontroller resources, so the computational resources of Arduino or ESP are not enough to control large LED screens. The use of an STM32 microcontroller allows you to control very large LED screens (up to 80 panels).
