There just wasn't enough room on the board to allow it to still fit in the space allocated for the <a href="http://en.wikipedia.org/wiki/Mobile_Daughter_Card">MDC1.5</a>.</li> </ol> <p><a href="http://erroraccessdenied.com/node/1665">read more</a></p> http://erroraccessdenied.com/node/1665#comments Microcontroller http://erroraccessdenied.com 701 702 93LC46 circuit design eee eeepc FT2232D FT2232H FT4232H geda gschem I2C MCP1703 pcb PCB design RS232 SPI UART Thu, 07 Jan 2010 11:18:11 -0700 Shadyman 1665 at http://erroraccessdenied.com
