numato

Numato, also known as Numato Lab, is a hardware company that designs and sells GPIO-based development boards and I/O hardware. The company focuses on providing affordable, easy-to-use devices for controlling external circuitry from computers and microcontrollers. Its product range includes USB and Ethernet based GPIO modules, relay boards, and programmable IO devices, as well as FPGA and microcontroller development boards. Many products are designed to offer plug-and-play operation with Windows, Linux, and macOS, and come with drivers, sample code, and documentation.

Numato boards typically provide multiple digital input/output channels, support for simple serial communications, and sometimes opto-isolation and level shifting for interfacing with different voltage domains. They are widely used in education, prototyping, automation, and hobbyist projects, enabling tasks such as turning relays on and off, reading switches, or controlling motors and sensors from a PC, Raspberry Pi, Arduino, or other host systems.

The company maintains an online catalog with product datasheets, manuals, application notes, and firmware examples. It also offers technical support through its website and forums. Numato emphasizes compatibility and open software resources, often providing example code in languages such as C, Python, and MATLAB to drive their I/O boards and modules. While not focused on consumer electronics, Numato's products are commonly used for rapid hardware prototyping and laboratory experiments where simple external I/O is required.
