From the project
Repository for the storage and dissemination of NN22 technical documents
This is a splitter board designed to be plug-compatible with the TIGRIS one. See top-level README for some more details.
Connector from readout system is a Samtec SHF-117-01-L-D-SM shrouded 34-pin header with 0.05" pitch.
Detector connector is Samtec SFMC-118-02-S-D 36-pin socket strip with 0.05" pitch. Note that the TIGRIS schematic and layout use mirrored pinout for the detector connector (odd-even swap).
