Raspberry Pi Datasheet ↗

The Raspberry Pi Compute Module 3+ (CM3+) upgrades the 200-pin DDR2 SODIMM industrial form factor (67.6 x 31.0 mm) with the 1.2 GHz 64-bit Broadcom BCM2837B0 quad-core Cortex-A53 SoC featuring an integrated metal heatspreader, improved thermal design, and 1 GB LPDDR2 SDRAM. It brings out 46 GPIOs across two independent 1.8V/3.3V reference banks (GPIO0-27_VDD and GPIO28-45_VDD), dual MIPI CSI-2 cameras, dual MIPI DSI displays, HDMI, and USB 2.0. Standard 8/16/32 GB variants wire SD0 internally to onboard eMMC, whereas CM3+ Lite routes the primary boot SDX bus to SODIMM Pins 4-24. Never apply 5V to any GPIO pin, power both GPIO_VDD rails on the carrier, and leave Pin 179 (VDD_CORE) unconnected.
