	~~NeoFromMatix Questions:~~
	* I would like to see a 0.1" pinout since this is much easier to solder and i can't see a large benefit of the molex connectors.
	* I would like it if we could flash the cape/F4 from the BBB

	* Is the plan to mount a Lisa/Mx on top of the BBB (just with an other board layout) or is this a completely new autopilot ? (for the second case we could use a larger MCU with more IO pins)

	*Do we need a power supply on the cape? It will increase cost quite a bit. If Lisa/M is still connected directly to peripherals it may as well get power from off-board, most vehicles already have a 5-6V servo bus		*Do we need a power supply on the cape?

			Neo: I thought the cape would have a voltage ragulator which can power the F4 and BBB. Maybe a different power rail for the servos.

	The SPI bus on the BB only can act as master. This would make the BB have to do busy loops polling the autopilot to check for data. I propose CAN as it has error detection and data framing.		*The SPI bus on the BB only can act as master. This would make the BB have to do busy loops polling the autopilot to check for data.

			*The lithium battery system only can act as a charger. The BB's power supply will not let it run on the nominal 3.6v of the lithium cell without a boosting SMPS.

added questions about power supply, Lia vs Lisa/M

New page

JKG Questions:
*Do we need a power supply on the cape? It will increase cost quite a bit. If Lisa/M is still connected directly to peripherals it may as well get power from off-board, most vehicles already have a 5-6V servo bus
* fully-populated Lia vs Lisa/M?
** Allows (almost) all connections to be broken out through the cape and BBB -- 0.1" header pins on Lia and sockets on cape with screws to lock boards together
*** much less wire nest
** no header pin access to ANALOG1 or ANALOG2
