At boot time this I2C interface will be interrogated to look for an EEPROM that identifes the attached board and allows automagic setup of the GPIOs (and optionally, Linux drivers). DO NOT USE these pins for anything other than attaching an I2C ID EEPROM. Leave unconnected if ID EEPROM not required. 5 4 3 2 © Raspberry Pi 2014 © Raspberry Pi 2014 © Raspberry Pi 2014 www.raspberrypi.org www.raspberrypi.org www.raspberrypi.org Title Title Title Drawn By Drawn By Drawn By Raspberry Pi B+ (Reduced Schematics) Raspberry Pi B+ (Reduced Schematics) Raspberry Pi B+ (Reduced Schematics) James Adams James Adams James Adams Size Size Size Ref Ref Ref A2 A2 A2 RPI-BPLUS RPI-BPLUS RPI-BPLUS Date: Date: Date: Thursday, July 10, 2014 Thursday, July 10, 2014 Thursday, July 10, 2014 1 Rev Rev Rev 1.2 1.2 1.2 Sheet Sheet Sheet 1 1 1 of of of 1 1 1 D C B A
