Descriptions

Relay Cape

The Relay Cape provides 4 3 amp capable relays with screw terminals. The relays are SPST, Normally Open. They are driven from GPIO lines.









Revision Changes

Revision A1

Initial version of the Relay Cape

Software Support & Compatibility

All revisions are compatible with BeagleBone and BeagleBone Black using 3.8 kernel.


Device tree overlay is coming soon.

Below is an example script to drive each relay in sequence:


import Adafruit_BBIO.GPIO as GPIO
import time

RELAY1 = "P9_12"
RELAY2 = "P9_15"
RELAY3 = "P9_23"
RELAY4 = "P9_27" 

GPIO.setup(RELAY1, GPIO.OUT)
GPIO.setup(RELAY2, GPIO.OUT)
GPIO.setup(RELAY3, GPIO.OUT)
GPIO.setup(RELAY4, GPIO.OUT)

a = [RELAY1, RELAY2, RELAY3, RELAY4]

while True:
        for x in a:
                GPIO.output(x, GPIO.HIGH)
                time.sleep(1)
                GPIO.output(x, GPIO.LOW)
                time.sleep(1)
