## <a name="Avionics Workshop Meeting Notes"></a><a name="Avionics Workshop Meeting Notes "></a> Avionics Workshop Meeting Notes 03/10/2002

----

In Attendance: Michael, Tim and Andrew

**Overview:**

We did another day of design on the various CAN nodes. We brought Michael up to speed, and discussed a ton of junk including:

- We hammered out the ciurcuit architecture of the Pyro node: See [[CanNodeSectionAppPyro]].
- We discussed the Power/Umbilical node: See [[CanNodeSectionAppPower]].

**Todo:**

- Michael will:
  - Delve into the SMB and SBS - understand how the charger, battery and host communicate.
  - Pick a smart battery (oh yeah, did I mention this at the meeting? ;), a level 2 charging chip.
  - and thus design the app section of the power (PWR) board.
  - Look for good CAN/Power and umbilical connectors.
  - Get Better.

- Tim will:
  - Design the various power circuits for the nodes:
    - 5V buck supply for all CAN nodes.
    - Boost supply for the battery backup on the pyro board.
    - NiMH charging and test circuit for the pyro boards.
    - Go nuts because he's got too much on his plate.

- Andrew will:
  - Lay out the processor section.
  - Layout the GPS section.
  - Layout the IMU app section.
  - Look into the magnetometer.
  - Solve the worlds problems by learning how to spell check these TWIKI pages.
