  IceCube-Gen2 is a planned extension to the existing IceCube Neutrino
Observatory and will provide an order of magnitude increase in the detection
rate of cosmic neutrinos by deploying ~10,000 sensors in a volume of ~8 cubic
kilometers. As part of the upcoming IceCube Upgrade, we are developing
prototype IceCube-Gen2 sensors to test all components in-situ in preparation
for mass production required for IceCube-Gen2. The novel IceCube-Gen2 module
will contain up to eighteen 4-inch photomultiplier tubes (PMTs). The signals
for each PMT are digitized with a 2-channel, 12-bit ADC (low- and high-gain) at
a rate of 60 MSps. In addition, each module contains LED flashers for in-ice
calibration, an FPGA for performing in-module local coincidence of PMT signals,
and onboard $\mu$SD flash memory for buffering data before it is sent to the
surface. In this contribution, we discuss the electronics and data acquisition
system design.
