I have some questions about my Arduino project.
I am using:
two A4988 boards to power two 17 Nema stepper motors:
Nema 17 Stepper Motor 48mm 42BYGH Stepping Motor 2A (17HS19 2004S1) Motor 4 lead 1m Cable for 3D Printer CNC XYZ Motor|nema 17|stepper motor nemastepper motor nema 17 - AliExpress
One bluetooth module JY-MCU
One L298N board to drive one 12V 50N Electromagnet
And a matrix of reed switches, but that isn't that important.
Now I want to power everything with a single 12V power supply/battery. What battery should I use and How should I wire it.
Sorry for my bad english.
