Abstract: A system may comprise a voltage upconverter, a universal serial bus (USB) connector to receive an input voltage from a USB port on a computing device, and a microfluidic diagnostic chip communication link to electrically couple the voltage upconverter to a microfluidic diagnostic chip wherein the voltage upconverter is to convert the input voltage to be received by the USB connector to an output voltage sufficient to drive a pump on the microfluidic diagnostic chip. A diagnostic system may comprise a microfluidic diagnostic chip comprising a pump and a voltage upconverter to receive an input voltage from a universal serial bus (USB) port of a computing device and to convert the input voltage into an output voltage that powers activation of the pump.

Abstract: A logic circuitry package for a replaceable print apparatus component comprises at least one logic circuit and an interface to communicate with a print apparatus logic circuit. The at least one logic circuit is configured to receive, via the interface, calibration parameters including an offset parameter and a sensor ID. The at least one logic circuit is configured to output, via the interface, a digital value corresponding to the sensor ID and offset based on the offset parameter.
