The GHI-USB engineering tool series from GHI Electronics, LLC, comprises a range of USB interface daughter cards and OEM boards designed to enhance connectivity and data acquisition capabilities in various engineering projects. These boards are particularly useful for hobbyists, researchers, and engineers who need to connect custom hardware to a PC via USB for control, data logging, or communication.

If you're working on projects that require precise control over external devices or need to interface with sensors and actuators, these boards offer a versatile solution. They support a wide array of protocols and can be easily integrated into existing systems. One thing worth noting is their flexibility; they often come with onboard microcontrollers that allow for custom firmware development, giving users more control over the hardware interaction.

Engineers tend to reach for this when they need a robust yet flexible USB interface for prototyping or production. The ability to add custom logic and functionality through the onboard microcontroller makes them a go-to choice for applications ranging from industrial automation to scientific research. Another practical benefit is their ease of use—these boards typically come with comprehensive libraries and examples, making it simpler to get started with complex USB-based projects.
