GBZ (Update: added homemade safe shutdown)

Hey sorry I hadn't planned on releasing my schematics or anything. Making this one was by far more expensive than buying cambles board, I just wanted to do it for the experience. If you're interested in making one i suggest doing a little research on high side switching and doing some prototypes.

Hey there! I'm a computer engineering student and I was looking into making similar circuits for some of my other projects. Obviously I'm not going to ask for your work because you put your time into it, but thank you for letting me know what to look up. Are there any other helpful tips you can give for me to look up so I can make something in my own? It would be really helpful as I've not used this type of circuitry before. You can pm if you feel more comfortable, thank you !

To help designing circuits like this a spice simulator such as ltspice is very nice as you can get models for the real parts and see if or how everything will work. Picking the correct parts is a little harder and takes a good amount of digging though data sheets. Look at some other parts you see people using and try to figure out why they chose it.

Yup already been looking more into it. Thanks. I forgot I have PSPICE available to me through my department. Haven't used it in a few years but I guess this is a good time to get into it haha
