Use uArm Controller without PC?

Is it possible to use the uArm Controller standalone without a connection to a PC?

I uploaded a sketch but when I unplugged the USB cable to the PC the program stopped responding.

You could connect the cable to the PC to another port which could provide power to the board.

I want to know how to power the controller without connection to a PC.

The controller board you sent is missing all the components in the 12V DC-DC 5V power supply circuit.

How do you suggest I power the board without a PC?

You could connect 5V power to this port

Is there a way to power the controller from the uArm?

No, maybe you could use a power bank or a 5v phone charger.


What is the current requirement of the uArm Controller from the 5V power supply?

An normal 5A1A is OK
