RequirementParameters

Power supply24V consistent with the HR detector

Mechanical size

We would like to match the ePixHRM board dimensions to reuse cooling

Side entrance detector

  • Existing 75x175mmx58:
  • max envelope would be (100x175x75mm)


Digital board2.56x5.265"

Power and communication2.56x5.240"

Carrier

2.56x1.95


Can we do it smaller?
