I need some guidance on connecting a PiicoDev Adapter for Raspberry Pi and a 5V 4 Channel Relay Module 10A to the same PI3 model B.
PiicoDev Adapter for Raspberry Pi will control:
PiicoDev Laser Distance Sensor VL53L1X
PiicoDev Atmospheric Sensor BME280
PiicoDev Ambient Light Sensor VEML6030
PiicoDev Buzzer Module
5V 4 Channel Relay Module 10A will control 3 Amphibious Horizontal Submersible Pump.
Just wondering if sufficient GPIO terminals will be available to run the relay module once the PiicoDev Adapter is connected. I need 3 GPIO terminals to control 3 relays and 1 GPIO terminal for a soil moisture sensors.
Electrically it shouldn’t be an issue (just watch out for address conflicts, and don’t forget to cut the pull-up resistors). One of these should get you out of trouble, as that module from DFRobot has the I2C pins broken out to male headers:
