Yocto-MaxiMicroVolt-Rx-C

The Yocto-MaxiMicroVolt-Rx-C is a precision analog/digital converter to perform high-precision differential voltage measurements. The device provides 4 differential inputs, which are measured in round-robin loop. It provides a regulated 4.7V power supply. The inputs are not electrically isolated from the USB ground, but the inputs can freely float between the ground and the 4.7V supply: only the voltage difference between the two wires of each pair will impact the measured value.

The measure is performed by a 32 bit A/D with FIR filter, which allows for a sensitivity better than 1 uV, combined with a precision voltage reference. The device includes a built-in temperature sensor, which can be internal or external NTC, and can perform autonomous computations on the measures values and temperature. This makes it ideal to measure the output signal from electrochemical gas sensors for instance.

The device provides immediate reading on USB, and can also store measures on the device internal flash for later retrieval when connected again by USB.

This module is the equivalent of the Yocto-MaxiMicroVolt-Rx, but with a USB type-C connector. Both versions can be connected to a USB A, Type C or Micro-B host with the appropriate cable.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.

USB cables and enclosures to be ordered separately.
