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 Title Title Title Size Size Size Raspberry Pi 3 Model A+ Reduced Raspberry Pi 3 Model A+ Reduced Raspberry Pi 3 Model A+ Reduced Ref Ref Ref A2 A2 A2 RPI-3A+ RPI-3A+ RPI-3A+ © Raspberry Pi 2018 © Raspberry Pi 2018 © Raspberry Pi 2018 www.raspberrypi.org www.raspberrypi.org www.raspberrypi.org Drawn By Drawn By Drawn By Roger Thornton Roger Thornton Roger Thornton Rev Rev Rev 1.0 1.0 1.0 Date: Date: Date: Thursday, November 08, 2018 Thursday, November 08, 2018 Thursday, November 08, 2018 1 Sheet Sheet Sheet 1 1 1 of of of 1 1 1 D C B A
