I have a small breadboard that has a L293D motor controller and 2 DC motors. The board is hooked up to a Nordic DK and everything on the PWM side is fine. The breadboard is powered by the development board's 5 V pin but I am ready to move to the next step of a PCB so I will need a battery.
I have two 2032 coin cells that were taped together and have jumpers for positive and negative but whenever I try to use it as the power source on the breadboard it fails to work. I checked it with a multimeter and it's throwing out at least 5.6 V.
Is there something I am missing? Are lithium batteries not applicable for this? Can I still make a PCB with what I have now?
