Yoctopuce, USB sensors and actuators

Meet Yoctopuce

Yoctopuce designs, manufactures and sells USB devices to let your computer sit in the real world, not in the cloud. Our USB modules are tiny, easy to install and easy to drive programmatically. Among them you will find:


Yocto-RS232USB to RS232 isolated adapter, with built-in data analyser. Works without driver and without COM port.
