This HCPL-817 opto-isolator provides a single isolated channel for letting a simple microcontroller switch an external load. It is useful when you want to separate low-voltage control electronics from circuits driving relays, small motors or similar loads.
The device comes in a 4-pin DIP through-hole package, making it straightforward to use on a breadboard, prototyping board or custom PCB. It can switch up to 50mA on its output channel.
Sold as an individual unit. A datasheet and example schematic are available from the supplier documentation.

Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
