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-4-20mA-TxIsolated 4-20mA generator. This is what you need to control by USB any device featuring a 4-20mA input.
