	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).

	* Nice to mate board-to-board with Lia, but should also be compatible with Lisa/M (perhaps at least mount lisa/m on the LGSB with 2mm hardware) [[User:Scdwyer\|Scdwyer]] 18:09, 23 August 2012 (UTC)		* Nice to mate board-to-board with Lia, but should also be compatible with Lisa/M (perhaps at least mount lisa/m on the LGSB with 2mm hardware) [[User:Scdwyer\|Scdwyer]] 18:09, 23 August 2012 (UTC)
