Raspberry Pi Datasheet ↗

Raspberry Pi Compute Module 5 (CM5 & CM5Lite) brings the quad-core 2.4 GHz Cortex-A76 BCM2712 SoC, RP1 PCIe southbridge, and Renesas DA9091 PMIC to the 55 × 40 mm dual 100-pin Hirose DF40C footprint. Connector J1 (Pins 1–100) carries +5V input, regulated CM5_3.3V and CM5_1.8V rails, VBAT RTC backup, USB-C PD CC1/CC2, PWM fan control, BCM54210PE Gigabit Ethernet pairs, SDIO (CM5Lite), and 28 RP1 GPIOs (5× SPI, 5× PL011 UART, 4× I2C, and 4-SM PIO). Connector J2 (Pins 101–200) exposes PCIe Gen 2/3 x1, two SuperSpeed USB 3.0 ports, USB 2.0 OTG, dual 4K60 HDMI, and two 4-lane bidirectional MIPI CSI-2/DSI transceivers. Tie GPIO_VREF (Pin 78) to CM5_3.3V or CM5_1.8V; GPIOs are never 5V tolerant, and PCIe_RX requires carrier AC coupling.
