The Relay Board gives your Raspberry Pi board the ability to control high voltage/high current devices, and easily makes normal home appliances become intelligent. Can be accessed programmatically or directly by shell.
Up to 4 layers can be stacked.The 4 Channel Relay uses high-quality relay modules combined with the most popular microcontroller technology to communicate with the Raspberry Pi..
You can use mulitiple relay modules stacked together to add many channels.
The 4 Channel module is very fast, easy to install, and supports multi-language development, making it ideal for smart home projects..

5V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current.
Equipped with high-current relay, AC250V 10A.
Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP432, TTL logic).
Indication LED's for Relay output status.

This Relay Delay Switch is easy to use when you are familar with the operation.
Relay Board has high precision, stable and reliable performance for your daily use and satisfaction.
There are many voltage and time range of the Relay Module for your choice, both "on" time and "off" time are adjustable.
Time Adjustable Delay Relay can be widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc.
With the Relay Module Controller, your life will be more intelligent and convenient.

Onboard high performance microcontroller chip.
Module with overcurrent protection and relay diode freewheel protection.
On-board 5V, 10A/250VAC, 10A/30VDC relay, long life of relay can be continuously sucked 100,000 times.

Turn on and off lamps, fans, solenoids, and other small appliances(up to 250VAC or DC power) using any Feather board.
Compared to Adafruit's smaller Relay FeatherWings, this can handle a beefy 1200 Watts.
Works with all/any of our Feather boards, just wire up the relay control pin to whatever GPIO you like.
Connect a FeatherWing on top of your Feather board with Feather Stacking Headers or Feather Female Headers.

Raspberry Pi Expansion Board, Power Relay.
The RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent..
Standard Raspberry Pi 40PIN GPIO extension header, Supports Raspberry Pi A+/B+/2B/3B/3B+/4B and later versions.
High quality relays, loads up to 5A 250V AC or 5A 30V DC.
Photo coupling isolation, prevent interference from high voltage circuit.

Have you ever wanted to control something powerful or have you ever needed to turn on/off a high power device from your Arduino compatible board or another low powered microcontroller? No soldering needed to get started. Plug and play. Code available. Small footprint..
The Single Relay board can handle up to 5.5A at 240VAC for long periods of time and allows you to control large power loads with simple I2C commands. Utilizing our handy Qwiic system, and on-board screw terminals, no soldering is required to connect it to the rest of your system!.
The Qwiic Relay comes with a default I2C address of 0x18 but can be changed with a simple command allowing you to control over 100 Qwiic Relays on a single bus (but please be aware that toggling lots of relays on a 3.3V bus can cause voltage spikes so an external power supply will be required)!.
In addition, there is an address jumper on the back of the board. Closing this jumper with solder will change the address to 0x19..
Operating Voltage: 1.7V-3.6V. Coil Resistance: 23.5Ω. I2C Address: 0x18 (Default), (Jumper changes to 0x19). Max Current (Through Relay): 5.5A (240 VAC).
