Board with Arduino Nano, 2 A4988 and 1 double output relay.
Screw terminals 5.08 for connection: in 12v, out 5v, LCD out, 2 stepper motor, 2x NO NC C Relay, 5 out with resistor for buttons, 1 out free.
This project is rework Schematics and PCB 3D Wire Bending Machine from [howtomechatronics](https://howtomechatronics.com/projects/arduino-3d-wire-bending-machine/)
- Adding servo connector
- Power regulator is used [Mini DC-DC 4.5-24V To 5V 3A](https://www.aliexpress.com/item/32768078949.html?spm=a2g0o.cart.0.0.10f63c00YJjLX9&mp=1)
This controller is absolutely cold in operation and allows power...
