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 4.7uH L1 SRN4018TA-4R7MH 2A 2.2uH L2 2A SRN2512-2R2M HDMI_T2P HDMI_T2N HDMI_T1P HDMI_T1N HDMI_T0P HDMI_T0N HDMI_CKP HDMI_CKN HDMI_CEC HDMI_SCL HDMI_SDA H5V HDMI_HPD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 3V3 PP8 C7 10u M1608 6.3V X5R 20% 1V8 PP9 C8 47u M2012 6.3V X5R 20% 0 2 1 2 J6 JTHDC-19F02A Mini HDMI CAM_GPIO0 CAM_GPIO1 SCL0 SDA0 1 H S 2 H S D2_SH D2+ D2- D1_SH D1+ D1- D0_SH D0+ D0- CLK_SH CLK+ CLK- CEC_GND CEC SCL SDA Reserved +5V HPD 3 H S 4 H S 1 5V_CORE VDD_CORE VDD_CORE L3 470nH C162 47u M2012 6.3V X5R 20% C163 10u M1608 6.3V X5R 20% PVIN PVIN PVIN SW1 SW2 FB PGND PGND PGND PGND A1 B1 C1 A2 B2 E3 A3 B3 C2 C3 U16 AVIN EN SCL SDA AGND RT8088AWSC J12 3V3 DDR_1V25 1V8 C20 220n M0603 6.3V X5R 20% C267 10u M1608 6.3V X5R 20% 4 6 U20 BIAS IN OUT 3 GND 2 EN PAD_GND NC RT9081A-1BGQZA(2) 1 5 7 C268 10u M1608 6.3V X5R 20% 2 D1 D2 E2 D3 E1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 5V_CORE C161 1u M0603 6.3V X5R 20% INT_SCL INT_SDA CAM1_DN0 CAM1_DP0 CAM1_DN1 CAM1_DP1 CAM1_CN CAM1_CP CAM_GPIO0 CAM_GPIO1 SCL0 SDA0 3V3 M00-718-001-022 3V3 R100 470 1% 1005 2 2 3 2 3V3 R24 1.8K 1% 1005 R23 1.8K 1% 1005 ID_SD ID_SC GPIO2 GPIO3 GPIO4 GPIO5 GPIO6 GPIO7 GPIO8 GPIO9 GPIO10 GPIO11 GPIO12 GPIO13 3V3 C67 220n M0603 6.3V X5R 20% U1C RP3A0 4 G 5 J I 2 O D D V I 2 O D D V N4 L4 M2 L3 M1 L2 K1 K3 F1 K2 F2 J2 H1 J4 GPIO0 GPIO1 GPIO2 GPIO3 GPIO4 GPIO5 GPIO6 GPIO7 GPIO8 GPIO9 GPIO10 GPIO11 GPIO12 GPIO13 GPIO14 GPIO15 GPIO16 GPIO17 GPIO18 GPIO19 GPIO20 GPIO21 GPIO22 GPIO23 GPIO24 GPIO25 GPIO26 GPIO27 E2 H2 E3 D1 H3 B1 D2 C2 B2 G3 C3 C4 F3 B10 GPIO14 GPIO15 GPIO16 GPIO17 GPIO18 GPIO19 GPIO20 GPIO21 GPIO22 GPIO23 GPIO24 GPIO25 GPIO26 GPIO27 D7 GREEN 1608 STATUS "ACT" LED STATUS_LED PP72 RUN RUN VC_TRST_N VC_TDI VC_TDO VC_TMS VC_TCK J5 1 2 3 4 5 6 7 8 NF Title Title Title Pi Zero 2 W Pi Zero 2 W Pi Zero 2 W Size Size Size Ref Ref Ref A3 A3 A3 RPI-ZERO2W_R1 RPI-ZERO2W_R1 RPI-ZERO2W_R1 Date: Date: Date: Friday, October 15, 2021 Friday, October 15, 2021 Friday, October 15, 2021 © Raspberry Pi 2017 © Raspberry Pi 2017 © Raspberry Pi 2017 www.raspberrypi.org www.raspberrypi.org www.raspberrypi.org Drawn By Drawn By Drawn By Simon Martin Simon Martin Simon Martin Rev Rev Rev R1 R1 R1 Sheet Sheet Sheet 1 1 1 1 of of of 1 1 1 D C B A
