Getting Started With BC Robotics Relay Breakouts
Our Relay Breakout boards are designed to allow microcontrollers (like the Arduino), single board computers (like the Raspberry Pi), and other low power / low current signals to switch high current / high power loads. Relays are one of the easiest ways to control a high current / high voltage load, but a relay cannot simply be connected to a microcontroller, they require several additional components to function correctly and protect the microcontroller from damage. Our breakout boards handle all of this extra circuitry in a compact, easy to use, module.
The boards are offered in a variety of coil voltages (the voltage used to power the relay) and have a wide input voltage for the relay trigger (the low power signal that controls the relay). On the relay contact side, each relay has the common, normally open, and normally closed pin broken out to a convenient 5.0mm pitch screw terminal. If this all sounds over your head, don’t worry, we will be going into this in great detail!
A Few Considerations:
When it comes to choosing relay breakout boards there are a few things to consider:
- What you are controlling (The voltage and current you want to switch on and off using the relay)
- What power you have available (To power the relay coils)
- What is the voltage of the signal you want to trigger the relay with
