8 Channel WiFi Relay Module - module with 8 relays and WiFi communication

A power module for the Pimoroni Yukon platform that allows independent control of two high-current outputs within a voltage range of 5 to 17 V. Built-in diodes and chokes enable excellent handling of inductive loads such as pumps, fans, and solenoids. Each channel can also operate in PWM mode, allowing for smooth power regulation in slow-response devices. The module supports a total current of up to 15 A and includes temperature sensors and a "power good" signal. Pimoroni PIM692

I/O module supporting Modbus RTU via USB and RS485 and Modbus TCP via Ethernet. It has 4 built-in SPST relays and 8 digital inputs, 8 digital outputs and 4 analog inputs. Provides a flexible DIN rail mounting system. Numato Lab NLRXE002-A

This SPST solid-state relay module allows for safe switching of DC circuits up to 60 V and 7 A, offering galvanic isolation and low conduction resistance (approx. 30 mΩ) thanks to the use of back-to-back MOSFET transistors. It features fast switching time (up to 1 ms), low control current consumption (approx. 10 mA), and the ability to control a signal from 2.7 to 40 V. Its compact design, lack of mechanical components, and the ability to mount on 2.54 mm connectors or screw terminals make the module a durable and quiet solution for systems requiring reliable isolation and long service life. Pololu 5420

Crowtail-MOSFET 2.0 enables controlling devices powered with up to 50 V DC using a low-voltage signal from a microcontroller. It is used in projects requiring power isolation or switching, such as fans, LED strips or DC motors.

The module is equipped with eight 10A / 250VAC relays controlled independently via a serial bus (UART) or from a PC (through a microUSB connector). The NO / NC contacts of the relays have been led to the ARK screw terminals. The board recommended for use with Arduino enables the control of eight relays using only two microcontroller lines.
