The White Rabbit protocol (WR), developed at CERN for the distribution of sub-nanosecond timing to thousands of nodes displaced over large geographic areas, is becoming increasingly reliable and is being utilized in various contexts, notably in modern multi-messenger astronomy experiments in progress such as KM3NeT, CTAO and ET. Currently,WR supports connectivity with 1 Gb/s Ethernet, both point-to-point and through WR-compliant network switches. However, the WR community is already planning new developments toward a full 10 GB/s infrastructure, with clear ideas on building a new PCIe network interface card (NIC) board to connect PCs to the WR network. Generally, WR compatible electronics for data acquisition are proprietary developments tailored to specific applications. INFN-Bologna and Perugia (University and INFN) are designing a set of low-cost electronic boards enabling versatile management and readout of commonly used sensors and actuators using WR technology for time-synchronization. We propose a lightweight dedicated mezzanine board, named Air-Plane, to complement the upcoming new NIC board and facilitate interface between legacy WR Node as well as with non-WR remote cards. This modular and highly scalable design will streamline the implementation of data acquisition systems in testing scenarios, such as ET mirror suspensions developments. In this contribution, we present the conceptual design of Air-Plane and its realization plan presented as parto of the M2TECH project, recently submitted to the HORIZON-INFRA-2024-TECH-01-01 call.
