this is my first time designing and ordering a PCB, so I'm quite nervous about this. So I thought you guys could have a look, since you are more experienced than me by far.
The PCB is for an enclosure I already picked out, and it will function as a CAN bus controlled relay controller.
I will use it in our EV conversion for the taillights. I designed it to be able to handle 5A, with appropriate external fuses.
The ADC pins are to measure the bulb resistances, to give a blown bulb light or not. I started another topic about the PSU unit, so I don't know much about this part.
Also, does anyone have an idea what's best to do with the GPIO0 pin on the ESP32?
I've made some changes, so here's the EasyEDA project: https://oshwlab.com/pol.peerboom/patrol-lcu
The schematic, now with upload header, all grounds connected and updated layout:
all pin 4's on the relays are the output lights in dutch, and all ADC nets are the voltage measurement for the resistance.
And here the updated board so far:
thanks so much!
