Power supply board

Ready for experimental visit to Trento, 28th September 2025

  • Power distribution board required for QuARC.
  • Provide power for Raspberry Pi and DDC boards from single DC input:
    • 5V/5A for Raspberry Pi via USB-C
    • >7.5V (5A?) for DDC board daisy chain via 2.5mm barrel
  • Single USB-C PD input: 20V/5A
    • Needs USB-C PD voltage negotiation chip
  • Fallback option with 20V DC 2.5mm barrel jack input
  • LEDs to indicate each voltage is provided correctly:
    • 20V input
    • 5V to Raspberry Pi
    • >7.5V to DDC boards
  • Should be able to switch off LEDs
  • Necessary to switch between input power supplies?
  • Ensure both power outputs stable: no drop-outs!
    • Potential for USB-C PD to drop out when voltage renegotiated?

Upon completion of Rev.F board

  • Integration of scintillating fibre profile monitor based on design from Blake Leverington, University of Heidelberg
  • Hamamatsu S17285 photodiode arrays to couple to scintillating fibres
  • Interface board needed between USB-C connection from FPGA and photodiode arrays
  • Acquire data; distribute timing signals
