Abstract	Both the trigger and the data acquisition systems of the Belle II experiment at the SuperKEKB collider in Tsukuba, Japan, are completely redesigned to cope with the considerably higher event and background rates compared to the previous Belle experiment. Belle II hardware (Level-1) trigger consists of several sub-triggers and a final decision logic, which issues the trigger with a fixed latency of about 5 \mus after bunch crossing. The data acquisition (DAQ) system reads the detector signals upon the Level-1 trigger decision and transfers the data from the front-end electronics to the storage system. In this presentation, we review the design of these two systems and describe the current state of their construction.
