5PCS MAX7219 8x8 Dot Matrix LED Display Module 5V 5-Pin Interface DIY Kit with MCU Control for Arduino and LED Matrix Projects (Green)
Key features
- High Performance LED Matrix Driver:This module is designed to efficiently drive a single 8x8 dot matrix common cathode LED display, providing high-quality visual output for your projects.
- Compatible with 5V Power Supply:Operates at 5V with stable performance and is compatible with a wide range of microcontrollers and development boards such as Arduino.
- Durable and Easy-to-Install Design:Features four screw holes with a 3mm diameter, allowing for secure mounting using M3 studs or screws, ensuring a stable setup for your projects.
- Compact and Space-Saving Module:Dimensions of 3.2cm x 3.2cm x 1.5cm make it perfect for projects where space is limited, while still maintaining high functionality.
- Expandable with Cascading Support:Equipped with input and output interfaces, this module allows for easy cascading of multiple units, enabling the creation of larger LED displays.
MAX7219 is an integrated serial input/output common cathode display driver. It connects microprocessors to 8-digit 7-segment LED displays, as well as bar graph displays or 64 individual LEDs. The device includes an on-chip B-type BCD encoder, a multiplex scan circuit, segment-word drivers, and an 8x8 static RAM for storing data. There is only one external register for setting the segment current of each LED.A convenient 4-wire serial interface allows connection to general-purpose microprocessors. Each data can be addressed without rewriting all displays during updates. MAX7219 also allows users to choose whether to encode or not encode each data.The entire device includes a low-power shutdown mode with 150μA, analog and digital brightness control, a scan limit register that allows users to display 1-8 digits of data, and a test mode where all LEDs light up.Module Parameters:A single module can drive an 8x8 common cathode dot matrix.Module operating voltage: 5V.Module dimensions: 3.2 cm (length) x 3.2 cm (width) x 1.3 cm (height).Features 4 screw holes with a diameter of 3mm.The module has input and output interfaces, supporting cascading of multiple modules.Wiring Instructions:The
Free shipping included. 30-day hassle-free returns.
