The IceCube Upgrade is the first step towards the next-generation neutrinoobservatory at the South Pole, IceCube-Gen2, and will be installed in thecentral region of the existing array. The Upgrade will consist of 693 newlydeveloped, densely spaced optical sensors and 50 standalone calibrationdevices, which will enhance IceCube's capabilities both at low and highneutrino energies. Of the new sensors, 402 will be multi-PMT Digital OpticalModules (mDOMs). Consisting of 24 small photomultipliers arranged inside apressure vessel, the mDOM features a large sensitive area distributed nearlyhomogeneously over the full solid angle. The use of multiple, individuallyread-out PMTs allows directional information to be obtained for the registeredphotons and enables the use of multiplicity triggering within a single module,e.g., for background suppression. The challenges driving the mDOM developmentincluded tight restrictions on module size, data-transfer rate, and powerconsumption as well as the harsh environment in the deep ice at the South Pole.In this contribution we present the final mDOM design that meets thesechallenges.
