|| [[Image(http://ohm.bu.edu/~hazen/APOLLO/figs/apollo_200.png)]] || This is a project to develop a common ATCA blade which can be used for readout and triggering applications in LHC experiments.  It is named after the Apollo program CSM spacecraft which separated into Command and Service modules. || [[Image(http://ohm.bu.edu/~hazen/APOLLO/gallery/cm.jpg, link=[http://ohm.bu.edu/~hazen/APOLLO/gallery/])]] [http://ohm.bu.edu/~hazen/APOLLO/gallery Photos] ||

== Debug Log ==
* [[Apollo RevA]] -- '''Please log all debugging activity here'''

== Aux boards ==
* [[ApolloClocksTestBreakout]] -- "PicoDTH" clocks breakout for ATCA J23
* [[DummyCommandModule]] -- Breakout/loopback for CM connectors

== Rev A Comments ==

* {{{EN_ONE_JTAG_CHAIN}}} should have a pull-up/down and/or jumper so something sensible happens when the IPMC is not installed or programmed.
* Serial comms between Zynq and CM should be possible without IPMC intervention.
* How to turn on payload power with no IPMC installed/running?
* JTAG (and other GPIO) signals must obey ENABLE/READY to avoid driving CM logic when not powered

Consider making mezzanine board 7U high (277.8 mm, see [https://en.wikipedia.org/wiki/Eurocard_(printed_circuit_board) Eurocard info]).  
Depth probably non-standard ~ 200mm as standard depths 160mm and 220mm are not convenient.
