Autopilot Discussion
Maybe use Lia instead of Lisa/M. Lia has the same circuitry as lisa/m (apart from the BMP barometer). Then we could use the 0.1" header pins to do board to board connections between lia and the Lisa Gumstix Breakout (LGB). Esden 21:01, 21 August 2012 (UTC)
IO Discussion
I2C
- Should we have I2C level shifters or anything on the breakout board? Esden 21:01, 21 August 2012 (UTC)
- Confirmed that it is needed. No isolation for I2C but levelshifting to 5V or 3.3V Esden 01:15, 23 August 2012 (UTC)
Minimum requirements
