Circuit diagram, PCB layout and code for an ATTiny85 powered, addressable RGB LED strip ... to handle up to 5A of current for PCBs fabricated at 1.6mm thickness and 1oz/mm2 allowing for LED strips of ...

The PCB layout if using a single LED array. When building this version I suggest fitting the LED bargraph last to make the board assembly easier. This board has one small link marked in red.

There are a few options to do similar things with PCB layout, including tscircuit. There’s a walk-through for using it to create an LED matrix and you can even try it out online, if you like.

Therefore, this research is committed to identifying device types through algorithms, Realize the modularization of PCB discrete devices, improve the patency of PCB circuit and save on-board space. In ...
