Technical overview

  • Resolution: 96 × 48 pixels (4608 individual RGB LEDs in total).
  • Pixel pitch: 2.5 mm; pixel format 1R1G1B.
  • Panel dimensions: 240 mm × 120 mm (the wiki also lists 160 × 160 mm in the features section – inconsistent).
  • Connections: two HUB75 headers (input/output), allowing chaining of multiple panels.
  • Power supply: 5 V / 2.5 A via VH4 header; power consumption ≤ 20 W.
  • Viewing angle: ≥ 140°; driving: synchronous, 1/24 scan.
  • Supported controller boards: Raspberry Pi, NodeMCU-32S (ESP32), Arduino Mega 2560 (Arduino Uno not recommended due to limited memory).
  • Included open-source demos: demo, c-example, minimal-example, text-example, pixel-mover, clock (for Raspberry Pi); SimpleTestShapes, BouncingSquares, AuroraDemo (for ESP32).

Notes and version constraints

  • The wiki lists conflicting panel dimensions (240×120 mm vs. 160×160 mm) – verify on the physical product.
  • This is a bare screen: a controller board such as Raspberry Pi, ESP32 or Arduino is required; these are not included.
  • Power supply must be strictly 5 V; other voltages can damage the display.
  • Different production batches may show slight differences in initial color output (some batches display a blue background).
  • Example demos sometimes reference other matrix sizes (e.g., 64×32, 64×64) only as reference images; actual display behavior depends on the hardware batch.
  • For ESP32 connection, the ESP32 board manager URL must be added in the Arduino IDE; path settings depend on the username.
  • The bending limit is about 29° – excessive bending can damage the PCB.
