Raspberry Pi board not included
The ModMyPi PiOT (Pi of Things) relay board is smart! Not quite Skynet smart, so you can tell John Connor to stay at home and play with his Raspberry Pi. But it's much smarter than your average relay board! We've created a Raspberry Pi Relay Board that does away with the complicated wiring and fiddly jumper configuration of your standard relay board, and bundles that control into an on-board PIC, making configuration faster, easier and safer. The PiOT relay board can be connected directly on top of the Pi, or via a GPIO ribbon cable (not included), and also features mounting points for the Raspberry Pi Zero. Each is board is fully assembled, and ready to plug and play! We also stock cases for the Raspberry Pi B+/2/3 & Raspberry Pi Zero.
The PiOT relay board allows you to bond a GPIO pin to a relay with the touch of a button. No need to tie pins using resistors, and no need to re-wire the circuit when you want to change which GPIO pin fires which relay. Simply select your GPIO pin using the on-board tactile buttons and two-digit 7-segment display, and switch that pin high or low to fire your designated relay!
The on-board display can be configured to show the Pi's BCM or Pin number system for GPIO/relay bonding, and also demonstrates visual feedback of the relay on/off status for easy monitoring. The display can also be used to test relays before configuring them with your Pi, in addition to providing menu access for setting configuration.
The PiOT relay board also features multiple innovative start-up modes designed to combat "chatter" on the GPIO which can lead to unexpected behavior. Variable delayed start-up allows users to pause activation of the relays for a short period during boot, ensuring that GPIO pins are correctly set prior to use, or the alternative handshake mode utilises a specific pulse train to enable activation and de-activation of the relay board at the user's will. No more accidental switching of relays at boot!
The PiOT relay board uses low current (~100mA) PWM (pulse width modulation) to significantly reduce the current required to hold the relays on when compared to other relay boards. This means that relay boards can be stacked up to 5 high without requiring additional external power.
Warning! Relays can be used to switch large voltages and currents. Please, please, please be careful when undertaking any work with this type of power - it can kill!
The ModMyPi PiOT Relay Board Features:
- 4 x OMRON G5LA-1 Relays for Switching up to 10A @ 250VAC, or 10A @ 24VDC
- 4 x Tactile Buttons for GPIO/Relay Bonding
- Two-Digit 7 Segment Display for Visual Feedback & Setting Control
- Micro-controlled GPIO/Relay Setting & Switching (No Jumpers Required!)
- 40 Point Raspberry Pi GPIO Modelled Input
- 5V & 3.3V Input Compatible
- Low Holding Current via PWM ~ 100mA per Relay Board
- Stackable Relay Board (Up to 5 Without External Power)
- Multiple Start-Up Modes to Negate Boot GPIO Chatter (Delayed/Handshake)
- Pi Zero Mounting Points
