The module is based on an STMicroelectronics STM32H745 microcontroller running the OpenIPMC open-source software. The mezzanine has been successfully tested on a variety of ATCA boards being proposed for the upgrade of the experiments at the HL-LHC, with its design and firmware being distributed under open-source hardware license.engControl and monitor systems online; Modular electronicsDetector control systems (detector and experiment monitoring and slow-control systems, architecture, hardware, algorithms, databases)Trabalho apresentado em evento10.1088/1748-0221/17/03/C030072-s2.0-85126568877
