in your schematic try and make all of your power symbols point upwards and your grounds point downward. that is a standard most designers have for the sake of readability. i'd look at one of the other boards in the github for a good reference. another small thing that is common is to connect your input bypass caps not exactly at your input connector. in the schematic, every node connected to +12v or GND is always connected so doing the bypass caps to the side is the same circuit layout as if you put the caps right next to the connector symbol. this is another thing that mainly helps with readability and making sure your schematic isn't cluttered. here is an example(sorry if this was worded terribly) an nmos is typically a low side driver. what this means is that usually the flow of current when using an nmos as a "switch" should go Power->Load(whatever you want to power)->NMOS->GND. This is because for an nmos, current flows when Vgs(voltage difference between gate to source) exceeds some threshold. In your current setup, this would mean that your gate would have to exceed 12v to turn on. In this circuit, this is not something we can do without external components to boost the voltage. Therefore, your nmos should be on the negative side of your load. In that setup, the voltage at the gate minus the source is just the voltage at the gate since the source is at 0. let me know if these comments make sense |
pls review :)
