The HiCCE wiki
HiCCE-128-FMC version 2
The second prototype of the HiCCE project.
The current status is we got two copies of the first draft board, and Andres and Maria Liz are validating it. During Andres' last stay, we discussed a number of potential revisions to the board.
First revision to the board.
The issues that arose during discussion of the first board are:
- do we have enough real estate? will it be enough to delete the jumpers or we need to enlarge the board beyond the spec?
- as configured we can neither electroplate nor measure impedance.
Some proposals on the table.
- Configure the board permanently for impedance measurement and delete all electroplating circuitry.
- Make the board larger to accommodate extra signals.
- Consider replacing the connectors with a high-density analog connector suited to attach a connector daughterboard or headstage.
- Add a connector with digital I/O for sync to behavioral rigs etc.
