This 2803 8x Relay & Step Motor Board uses the ULN2803 (an array of Darlington transistors), providing a crucial link between your Raspberry Pi's GPIO pins and the external world. This module allows you to control higher voltage and current devices directly from low-voltage and low-current Raspberry Pi GPIO pins. It's perfect for running motors, driving relays, powering LEDs, and more, directly from your Raspberry Pi.
Features
- The step motor connector can use the step motor (28BYJ-48 5VDC)
J12 (5V, D0, D1, D2, D3) and J19 (5V, D4, D5, D6, D7)
- Can disable the relay when using the step motor connector with jumpers (J15, J17, J25, J24, J34, J35, J36, J37)
- When you plug in the jumpers, it enables the relay. When you unplug the jumps, it disables the relay.
- U5 ULN2803 Eight Darlington transistors
Specification
- Output ports: J11, GND, D0, D1, D2, D3, D4, D5, D6, D7
- D0~D7 signals with status LEDs
- GPIO 17, 18, 27, 22, 23, 24, 25, 4 control D0~D7
