Here is a reference guide: http://www.electrodragon.com/w/Stepstick_Stepper_Driver_Board_A4988_V2
Connection details:
Connect the reset and sleep pins together.
VDD to +5V on the Croduino
GND to ground on the Croduino
1A and 1B to one motor coil
2A and 2B to the other motor coil
VMOT to external power supply (maximum 35V)
GRD to ground of the external power supply
STEP and DIR connect to the Croduino according to your code. Based on the reference code, STEP goes to pin 13 and DIR goes to pin 12.
To identify which pairs of wires belong together (1A and 1B, 2A and 2B), use a multimeter set to measure resistance. Select one wire and find its pair by measuring the resistance between wires - the correct pair will show only a few ohms (0-200 Ω). Verify the same for the other two wires.

ako se ne varam već smo Vam slali ovaj link: http://www.electrodragon.com/w/Stepstick_Stepper_Driver_Board_A4988_V2
Pinove reset i sleep spojite zajedno
VDD na +5V Croduina
GND na gnd Croduina
1A i 1B na jednu zavojnicu
2A i 2B na drugu
VMOT na vanjsko napajanje (ako se dobro sječam rekli ste 12V - makximalno 35V)
GRD na gnd vanjskog napajanja
STEP i DIR idu na Croduino kako ste zadali u kodu, prema kodu s linka STEP na pin13 i DIR na pin12
Ako niste sigurni koji su parovi žica s motora (1A i 1B, 2A i 2B) uzmite multimetar i namjestite da mejri otpor. Odaberite jednu žicu i njezin par ćete naći kada da otpor između njih dvije bude svega nekoliko Ohma (0-200). Provjerite da za druge dvije žice vrijedi isto.
