Motherboard By NESPi

• This relay module is applicable to the whole series of Raspberry Pi. Through this module, Raspberry Pi can control high voltage or high current equipment, such as light, water pumps, heaters, etc. This module is built with an AC/DC circuit, which can power the Raspberry Pi from high voltage, making it more suitable for situations where external power is not convenient.
• This module uses the standard Raspberry Pi GPIO interface, plug and play. At the same time, it still reserves extended needle arrangement and supports multi module stacking.
• It uses an optocoupler isolation chip, which can confirm that the control circuit is isolated from the high-voltage circuit to avoid burning the Raspberry Pi. It is equipped with LED status indicator, and the working status of each channel can be seen directly.
• It supports three output channels, each with a normally open port and a normally closed port, suitable for different application scenarios. The channel uses P25, P28, P29 pins by default, and the control pin can also be set in the form of jumper.
• Package content: relay module(with AC/DC) 1 Hexagonal screw 4?
