Raspberry Pi - 2803 2 Relay & Step Motor Board







                         connect to two 28BYJ-48 5V   DC STEP MOTOR


1. J2 J3  Step motor connector J2 (5V,D0,D1,D2,D3)  J3(5V,D4,D5,D6,D7) 

      can use Step motor (28BYJ-48 5VDC)

2. J20   5V,GND, D0, D1,D2,D3,D4,D5,D6,D7   OUTPUT

3. U5 ULN2803 8 darlington transistor array

4.  JP4 choose 5V input from Mini USB Port J7 or RS-Pi 5V

5. J7  Mini USB 5V input



    U5 uln2803  use  RS-Pi  pin 11,12,13,15,16,18,22,7 as GPIO 0 to GPIO7
