So once before I had a pcb made and although it was cheap and I only made 10 or 20, I made improvements and don’t want to have another 20 pieces made yet.
So I have a Nano on a through- hole which will have a mosfet and a resistor and then the l298n. What I will connect to the nano through-hole board with be the 7.4v battery pack and what I’ll connect to the l298 is a dc motor.
Trying to keep the form factor small, I’m trying to make the 2 main parts face opposite each other. I have here the image of it hand held but I’d like to get your opinions as to how to make these electrically isolated and stick together :
