Where do I sign up for e.g. 3 v2 CAB boards complete with LTC6904 and ADS1115? Do you make the schematic and MSP430F21x2 source code accessible? Why not an ARM-microcontroller instead of MSP430F21x2 - or the Openmoko ARM itself ;-) ? (Please note: curiosity is driving this question) Please do not redirect to the article from this discussion page. --Glenn 13:43, 17 July 2010 (UTC)
