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):
- Rev C schematic: Blade_FP.pdf
- Would like to support SD 3.0. See for example the MPI_usb_sdcard.pdf schematic
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.
