  2. Physical layout of PDM board EUSO-Balloon PDM board(NEW) HK (Temp., ASIC voltage, FPGA voltage, HV voltage) Jtag connector UFFO UBAT digital board(OLD) EC Connector 1 EC Connector 1 EC Connector 1 EC Connector 1 EC Connector 1 EC Connector 1 Power supply (regulator) Power connector 9pin D-Sub right angle male Power connector 160mmmm 160mm CCB interface connector OSC FPGA HK connector SRAM HVPS connector Power supply (regulator) 130mm 130mm Front side Back side JEM-EUSO PDM Board Back side JEM-EUSO PDM Board Front side • - In PDM board, most components have similar. The changes are connector. • - The components model name are ; • FPGA : A3PE3000L-FG896 • SRAM : 3DSR16M32VS4085 • - The interface connectors model name are ; • Between PDM and CCB : MicroD MDM with 37 pins(?) • Between EC and PDM : FX2- 120S-127SV with 120 pins(?) • Power and J-tag : DEMM 9PD(DEMM 9SD)(?)

  3. PDM board-ASIC EC board connector ① PDM board ② ③ FX2-120S-12SV size : ~1cm x ~10cm (Datasheet value is a little small) ①, ②, ③ width : ~1cm FX2-120S-127SV connector is possible. But the FX2-120S-127 connector clustered together in the corner of the PDM board. Because, FPGA and SRAM need via hole. Because the connector is too big, the available space for PDM board’s function are quite limited. So is there any possibility to the smallest connector? We are afraid that the cable maybe will not be flexible. 160cm FX2- 120S-127SV 1 ~1.7cm SRAM ① ~3cm FX2- 120S-127SV 2 FPGA FX2- 120S-127SV 3 ~3.2cm ② FX2- 120S-127SV 4 ~3.2cm 130cm FX2- 120S-127SV 5 ③ ~1cm FX2- 120S-127SV 6 ~10cm CCB connector Power connector

  4. PDM board thickness The highest component is D-SUB connector. PDM board PCB + D-SUB connector height : 1.6cm 1.6cm
