Operating since 2004, the Pierre Auger Observatory has led to major advances in our
understanding of the ultra-high-energy cosmic rays. The latest findings have revealed new insights
that led to the upgrade of the Observatory, with the primary goal of obtaining information on the
primary mass of the most energetic cosmic rays on a shower-by-shower basis. In the framework
of the upgrade, called AugerPrime, the 1660 water-Cherenkov detectors of the surface array are
equipped with plastic scintillators and radio antennas, allowing us to enhance the composition
sensitivity. To accommodate new detectors and to increase experimental capabilities, the electronics
is also upgraded. This includes better timing with up-to-date GPS receivers, higher sampling
frequency, increased dynamic range, and more powerful local processing of the data. In this paper,
the design characteristics of the new electronics and the enhanced dynamic range will be described.
The manufacturing and test processes will be outlined and the test results will be discussed. The
calibration of the SD detector and various performance parameters obtained from the analysis of the
first commissioning data will also be presented.
