Description

This device is an USB to I2C adapter, it will allow you to query circuits through an I2C bus. If needed, the Yocto-I2C can act as a voltage source to power the external circuit with 1.8V, 3.3V or 5V. The I2C communication can be configured to 1.8V or 3.3V. The Yocto-I2C can act as an I2C master only, not an I2C slave.

The Yocto-I2C can autonomously query and parse I2C data coming from any external I2C sensor and expose measures as if they were coming from a Yoctopuce sensor, with all the inherent advantages: unique identifier, polling, callbacks, data logger. Be aware that this device does not work with applications designed to use a COM port: it is designed to be used with Yoctopuce API only.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
