A Translator board translates all LVTTL signals to LVDS and vice versa. This interfaces DAQ with FEE boards. All the FEE boards and Translators are mounted on a backplane PCB carrying all LVTTL signals and low voltage segmentation. The entire readout is organized on 48 modules with each module comprising 4608 channels. Each module is divided in to 6 chains each reading 768 channels. The low voltage segmentation for the module is done using a low voltage distribution board. 

Fee board: Top and bottom copper
