Customer Questions & Answers

What are the exact dimensions of the matrix and what is included in the box when you receive the product?

The module measures 32 mm high, 129 mm long and 14 mm deep. The box includes the assembled matrix and the pins/connectors needed for integration. Jumper wires and a physical manual are usually not included.

Is it compatible with 3.3V microcontrollers and which pins are required for connection?

The module is designed to operate at 5 V, so connecting 3.3 V signals directly may result in it not being recognised or in unstable operation. A logic level converter is recommended. The required pins are: VCC (5V), GND (ground), DIN (data), CS (chip select), CLK (clock).

How is it installed and what is the best practice to ensure the module is not damaged during use?

It is recommended to solder the pins carefully to avoid short circuits and to connect the power supply always at the specified voltage. Good practice is to add current-limiting resistors if several modules are combined and to avoid exposing the circuit to moisture or overcurrent. The light should be kept within the specified values to prevent overheating.

What performance can be expected in terms of refresh rate and visibility, and what are the typical operating limits?

The MAX7219 allows a refresh rate of up to 800 Hz, sufficient for stable images without visible flicker to the naked eye. The module works optimally between 0–50 °C and the 5V supply must not be exceeded, nor the total current recommended in the datasheet (generally around 320 mA for 32 LEDs lit simultaneously).

Which boards is this 8x8 dot matrix module compatible with?

This module is compatible with Arduino boards and Raspberry Pi, operating at 5V.

What type of controller does this module use?

It uses the MAX7219 controller, which makes LED matrix control easier by reducing the number of pins needed.

What are the module dimensions?

The module measures 32 x 129 x 14 mm, which makes it easy to integrate into compact projects.

What kind of information can be shown on this display?

Text, numbers and simple graphics can be shown, ideal for tickers and information displays.

How is the module connected to an Arduino or Raspberry Pi board?

It connects via the VCC, GND, DIN, CS and CLK pins, following the standard connections for this type of module.
