The first proof of concept single-channel small area prototype was able to achieve time resolution below 25 ps. One of the crucial aspects in the development of the precise timing gaseous detectors applicable in high-energy physics experiments is a modular design that enables large area coverage. The first 19-channel multi-pad prototype with an active area of approximately 10 cm2 suffered from degraded timing resolution due to the non-uniformity of the preamplification gap. A new 100 cm2 detector module with 100 channels based on a rigid hybrid ceramic/FR4 Micromegas board for improved drift gap uniformity was developed. Initial measurements with 80 GeV/c muons showed improvements in timing response over measured pads and a time resolution below 25 ps. More recent measurements with a new thinner drift gap detector module and newly developed RF pulse amplifiers show that the resolution can be enhanced to a level of 17 ps. This work will present the development of the detector from structural simulations, design, and beam test commissioning with a focus on the timing performance of a thinner drift gap detector module in combination with new electronics using an automated timing scan method. %G English %Z RD51 collaboration %2 https://cea.hal.science/cea-04077382/document %2 https://cea.hal.science/cea-04077382/file/arXiv_AUtrobicic.pdf %L cea-04077382 %U https://cea.hal.science/cea-04077382 %~ CEA %~ CNRS %~ OPENAIRE %~ DSM-IRFU %~ DRT %~ IRAMIS-LIDYL %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ CEA-DRF %~ LIST %~ DM2I %~ UNIVERSITE-PARIS-SACLAY %~ IRAMIS %~ GS-CHIMIE %~ GS-COMPUTER-SCIENCE %~ GS-PHYSIQUE %~ DIN
