This page has documentation for the front panel board on the APOLLO blade service module. This is a small PCB which provides a reset/control button, USB console interface and uSD card.

Notes for Rev D

(starting design March 2020):

Level translators:

  • NVT4857UK - Looks promising, "auto-direction"
  • IP4856CX25/CZ (MPI uses). Needs a bunch of extra signals.
  • T6G3244ME

All are only available in a 0.4mm pitch BGA package and they claim you must use laser-drilled micro vias. We'd like to experiment with a layout using only mechanical (drilled) vias.
