Building and testing a module with 8 digits LEDs drived by MAX7219.
This project aims to build and test an 8-digit LED module, 0.56 inches, drived by MAX2719. There are 2 variants, THT and SMD. PCBs are designed with KiCad program and are given together with Wiring Diagram and assembly details. There is also a test program, which will be uploaded on an Arduino board and will allow a detailed visual check of the module. More on:https://www.instructables.com/56inch-LEDs-Display-With-MAX7219/
