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.

Provides constant voltage, protects from voltage and amperage spikes and prevents the fan from back feeding voltage through the vehicle's wire harness.
Threaded thermostatic switch that screws into the engine block or intake manifold for a professional looking installation.
Inexpensive protection for an electric fan and a vehicle's wire harness.
Kit includes weatherproof: SPST 35-amp relay, 30-amp circuit breaker and relay base with harness (6' input/2' output).
thermostatic switch, adapter, heat-shrinkable crimp-on terminals and mounting hardware.
Thermostatic switch turns on at 185 degrees and off at 175 degrees.

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).

Onboard square USB interface, stable connection..
Use imported high performance USB control chip..
Use the special relay drive chip ULN2803, the relay works more stable..
