I am currently designing a circuit for a custom pcb.
I am completely self-taught and still very inexperienced with electronics, so I was hoping I could receive some input regarding whether this circuit will actually work. It is largely based on a schematic for an old version of the Wemos D1 mini I found online.
The PCB is intended to be a visual representation of my city's train system. It's powered and programmed via micro USB, the brain is an ESP-12F that connects to a MAX7219N so that I can address each LED on the board individually.
Let me know if there is any additional information that you would need in order to better assess my schematic.
Thanks so much in advance!
