There are provided a drive board and so on capable of achieving reduction in size. A drive board according to an embodiment of the present disclosure is a board configured to output a drive signal to be applied to a liquid jet head having a plurality of nozzles, including a plurality of drive devices configured to generate the drive signal for jetting liquid from the nozzles. The plurality of nozzles is separated into a plurality of nozzle groups, and the plurality of drive devices is each configured to generate the drive signal to be applied to corresponding one or more of the nozzle groups. The plurality of drive devices and the plurality of nozzle groups are electrically coupled to each other, and the plurality of drive devices are arranged side by side along a predetermined direction.

Drive board, liquid jet head, and liquid jet recording device

There are provided a liquid jet head and so on capable of enhancing the reliability. A liquid jet head according to an embodiment of the present disclosure includes a jet section configured to jet liquid, at least one drive circuit configured to output a drive signal used to jet the liquid to the jet section, a differential input line configured to transmit data from an outside of the liquid jet head toward the drive circuit, a differential output line configured to transmit data from the drive circuit toward the outside of the liquid jet head, a coupling part which is arranged between the outside of the liquid jet head and the drive circuit, and to which the differential input line and the differential output line are individually coupled, and a detection circuit configured to perform detection of a coupling state in the coupling part using a transmission signal in at least one of the differential output line and the differential input line.
