Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> 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.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL22101 WSAL22101 – RGB Full-Color LED Matrix Panel, 4mm Pitch, 64×32 Pixels, Adjustable Brightness]<br /> <br /> == Technical overview ==<br /> * Resolution: 64 × 32 pixels = 2048 individual RGB LEDs; pixel form 1R1G1B for full-color display.<br /> * Pixel pitch: 4 mm; panel dimensions: 256 mm × 128 mm.<br /> * Driving: Synchronous operation with 1/16 row scan; viewing angle ≥ 160°.<br /> * Two HUB75 headers: one for controller data input, one for output/cascading.<br /> * HUB75 pinout: VCC (5V), GND, R1/R2, G1/G2, B1/B2, A–E (row select), CLK, LAT/STB, OE.<br /> * Power supply: 5 V / 4 A via the VH4 header; power consumption ≤ 20 W.<br /> * 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.<br /> * Use cases: DIY desktop or wall-mount display, signboard, environment monitor.<br /> <br /> == Notes and version constraints ==<br /> * Only 5 V power supply is permitted; other voltages may damage the panel.<br /> * 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.<br /> * For ESP32 demos: Wi-Fi calibration requires valid credentials; without a connection, the clock will not display correctly.<br /> * STM32 operation requires an external 5 V / 4 A power supply; otherwise IO malfunctions may occur.<br /> * Font sizes: Currently only 16×16, 32×32, and 64×64 are supported.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/RGB-Matrix-P4-64x32 RGB-Matrix-P4-64x32 - Waveshare Wiki]<br /> * Source revision: 110761<br /> * Captured: 2026-09-03T03:39:27+00:00<br /> * SHA-256: &lt;code&gt;879e8a1ffcde8441a29cad8a2fb1f0a7c6bd0ce66fc509722be51ab9b19eee1b&lt;/code&gt;</div>
