Hydraulic unit and brake system

A hydraulic unit comprising:

• a hydraulic block including a cylinder bore provided with a master cylinder connected to a brake pedal, a motor bore provided with a motor that generates hydraulic pressure by operating by an electrical signal output corresponding to displacement of the brake pedal, a hydraulic flow path, and a valve bore provided with a valve that controls a flow of a pressurized medium through the hydraulic flow path;
• and
• an electronic control unit configured to control operation of the motor and the valve based on information on the displacement of the brake pedal,
• wherein the motor bore is provided on a first surface of the hydraulic block and a housing of the electronic control unit is provided on a second surface of the hydraulic block opposite to the first surface,
• the electronic control unit includes a first circuit board and a second circuit board,
• a first connector configured to supply electric power or transmit an electrical signal to the first circuit board is positioned on an upper side of a third surface forming an upper surface between the first surface and the second surface, and
• a second connector configured to supply electric power or transmit an electrical signal to the second circuit board is positioned on a front side of a fourth surface forming a front surface between the first surface and the second surface.
