Description

This schematic has a few functions to this circuit. This circuit takes voltages starting from 4V to a max. of 13V. It was an open source project I found online. I've redone this board's schematic. But when it came to de PCB design I kinda lost it. I got as close to sorting the components on the board, but I didn't know where to start connecting wires or how. I'm taking a little break, but if anyone could connect all the components together on the PCB design and just let me know how it went, I would really appreciate it! I'm new to this hobby and reaching out online for some help. Lastly, if the connections are made, is there a way to simulate this board. Like it's running, power going through it, but simulated? Or a way to check the wiring of the schematic. Anyway I would really appreciate all the help, just message me or reshare for others to check/modify and/or use this board. Thank you
