Hello Everyone,
I have made a custom pcb that is attached on top of a Arduino MEGA to control a robotic Arm. The Custom PCB is only fit for 3.5 amps(12 volts) of battery supply and I have a 6 amp(12 volts) power supply. If I connect this battery to two of the same custom PCBs will it still work and divide the amp equally.
Thank you so much ahead of time!

Each board will draw the current it needs.
If that is more than the supply can provide, then: the supply voltage may droop; the output may get “dirty”; the output may shutdown until the load is reduced; the supply may overheat and shutdown until the load is reduced.
I am surprised you made a board without prototyping it first. It appears you did a design and are looking for an application. You can always put a fuse in line with each board to protect it. The boards do not have to be the same nor do they have to draw the same current. You might include a schematic not a frizzy thing if you need more help.

If they try to draw 3.5A each there will be problems. Don’t skimp on power supply capability - if
each board can draw upto 3.5A, a 10A supply is the right sort of value to go for - comfortably able
to handle 7A continuously without getting hot.
