The Numato Lab GPIO-USB modules are comprehensive hardware extensions that allow you to control various electrical devices from a smartphone or computer. The design of the Numato Lab GPIO-USB modules is adapted to control both AC and DC-powered devices such as household appliances and home automation systems. Numato Lab GPIO-USB boards communication is done using a USB A-type connector. The Printed Circuit Board has a set of analogue and digital input/outputs, through which the Numato Lab module communicates with external devices. The manufacturer provides excellent technical support and provides sample program codes on the basis of which the user can design even a very advanced application controlling physical objects. GPIO-USB modules offered by Botland store allow, among others creating a lighting controller or measuring system that captures the measurement signals from the sensors with a built-in analogue-to-digital converter (ADC) for further signal processing and making further decisions.
