Neo Debug Board Schematics or Pinouts
Hi folks, I will like to to have a peek at the Neo debug board's schematics or pinouts. I need to access the uarts as well as the jtag. Does anyone have any idea? -- Kiam Peng ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

RE: Neo Debug Board Schematics or Pinouts
Are these signals TTL level or are they already RS-232? If they are TTL, is there any reason I could not use the BrainStem from Acroname (http://www.acroname.com/robotics/parts/S13-SERIAL-INT-CONN.html) to overcome this? (That device only uses TXD, RXD, and of course power and ground). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joachim Steiger Sent: Saturday, August 18, 2007 2:43 PM To: community@lists.openmoko.org; [EMAIL PROTECTED] Subject: Re: Neo Debug Board Schematics or Pinouts wee.kiampeng wrote: > Hi folks, > > I will like to to have a peek at the Neo debug board's schematics or > pinouts.
