== Summary ==
The RGB-Matrix-P2.5-64x64 is a full-color 64×64 LED panel with 4096 pixels and 2.5 mm pitch. It connects to controllers such as Raspberry Pi, ESP32 or Arduino via HUB75 headers.

* [https://shop.jw-tech.eu/p/WSAL23708 WSAL23708 – RGB full-color LED matrix panel, 2.5mm Pitch, 64x64 pixels, adjustable brightness]

== Technical overview ==
* Full-color display with 4096 individual LEDs (1R1G1B per pixel).
* Pixel pitch: 2.5 mm; resolution 64 × 64 pixels.
* Panel dimensions: 160 mm × 160 mm.
* Two onboard HUB75 headers: one for controller data input, one for chaining additional panels.
* Expected power supply: 5 V / 3 A via a VH4 header; maximum power consumption ≤ 20 W.
* Viewing angle at least 140°.
* Controller compatibility per manufacturer: Raspberry Pi, Raspberry Pi Pico (CircuitPython), ESP32 (NodeMCU-32S), Arduino Mega 2560 and STM32F103RB.
* For Raspberry Pi operation, the open-source project rpi-rgb-led-matrix from GitHub is used; demos are run with sudo after compiling.
* When using Raspberry Pi Pico, CircuitPython with Mu Editor is recommended as the development environment.
* When connecting multiple panels to a Raspberry Pi, additional pin assignments are required for the second and third display boards.

== Notes and version constraints ==
* Power supply must be exactly 5 V; other voltages may damage the panel.
* Actual PCB layout can vary slightly between production batches; the delivered unit is authoritative.
* Raspberry Pi can share up to three panels; when using only one panel, connect only the pins marked with 😄.
* Demo commands assume the project has been compiled beforehand.
* When using STM32, an external 5 V / 4 A power supply is recommended to avoid I/O malfunctions.
* Not all listed controllers were explicitly tested in the source; compatibility claims come from the manufacturer.
* No warranty, certification, or pricing information is present in the source document; these must be confirmed separately.
