== Summary ==
The RGB-Matrix-P2.5-64x32 is a full-color LED matrix display with 64×32 pixels and a 2.5 mm pitch. It contains 2048 individual RGB LEDs (1R1G1B) and is driven via HUB75 headers. The display is a bare board without integrated controller electronics and requires an external controller such as Raspberry Pi, Pico, ESP32 or Arduino.

== Notes and version constraints ==
* The power supply must be exactly 5 V; other voltages can damage the display.
* Different PCB batches may have minor differences in silkscreen and layout; software remains compatible, but the actual delivery takes precedence.
* When connecting multiple panels to one Raspberry Pi, enable and data pins must be wired accordingly depending on panel count; for a single panel only the pins marked with 😄 are needed.
* Demo commands assume the rpi-rgb-led-matrix open-source project is installed; version differences in the project may cause incompatibilities.
* Using isolcpus=3 in /boot/cmdline.txt is recommended to improve display refresh rate; this requires a reboot and should be verified before use.
* For the Pico variant, the CircuitPython firmware must first be flashed via BOOTSEL + USB; without this step no demo will run.
* When using the STM32, an external 5 V / 4 A power supply is required, otherwise IO malfunctions may occur.
* Supported font sizes are currently limited to 16×16, 32×32 and 64×64; larger renderings are not guaranteed.
