== Summary ==
The RGB-Matrix-P4-64x32 is a full-color LED matrix panel with 64×32 pixels (2048 dots) and a 4 mm pitch. It is driven via HUB75 connectors and can be operated with Raspberry Pi, Arduino, or ESP32.

== Technical overview ==
* Resolution: 64 × 32 pixels = 2048 individual RGB LEDs; pixel form 1R1G1B for full-color display.
* Pixel pitch: 4 mm; panel dimensions: 256 mm × 128 mm.
* Driving: Synchronous operation with 1/16 row scan; viewing angle ≥ 160°.
* Two HUB75 headers: one for controller data input, one for output/cascading.
* HUB75 pinout: VCC (5V), GND, R1/R2, G1/G2, B1/B2, A–E (row select), CLK, LAT/STB, OE.
* Power supply: 5 V / 4 A via the VH4 header; power consumption ≤ 20 W.
* Compatibility: The panel is a bare screen without an onboard controller; it requires an external control board such as Raspberry Pi, Arduino Mega, or ESP32.
* Use cases: DIY desktop or wall-mount display, signboard, environment monitor.

== Notes and version constraints ==
* Only 5 V power supply is permitted; other voltages may damage the panel.
* The source references demos for multiple matrix sizes (P2/P3/P4); the exact pin mapping for P4 versus other variants must be confirmed in the respective hardware wiring diagram.
* For ESP32 demos: Wi-Fi calibration requires valid credentials; without a connection, the clock will not display correctly.
* STM32 operation requires an external 5 V / 4 A power supply; otherwise IO malfunctions may occur.
* Font sizes: Currently only 16×16, 32×32, and 64×64 are supported.
