- Form factor: 67.6 mm × 31.0 mm DDR2-SODIMM compatible connector form factor
- Networking: Ethernet via external PHY on carrier board
- USB: 1× USB 2.0 (High Speed)
- GPIO: up to 46 GPIO signals incl. UART/I2C/SPI/PWM/SDIO
- Video: 1× HDMI 2.0 (up to 4Kp60)
- Camera/Display: 2-lane and 4-lane MIPI CSI/DSI interfaces
- Multimedia: H.265 4Kp60 decode, H.264 1080p60 decode / 1080p30 encode, OpenGL ES 3.0
- Power input: VBAT 2.5 V – 5 V and 3.3 V supply via carrier board
- Operating temperature: designed for reliable operation at typical ambient temperatures
- Production lifetime: in production until at least January 2034
Typical applications
The Raspberry Pi Compute Module 4S is suitable for industrial control systems, embedded devices and volume products, especially as an upgrade option for existing Compute Module 3 designs. The compatible SO-DIMM form factor allows existing hardware to be reused while providing increased processing performance and memory capacity. Separating the compute module and carrier board enables flexible adaptation to project-specific interfaces and requirements.
Notes
Cables and power supplies must comply with applicable standards in the country of use. Operate in a well-ventilated environment; avoid contact with conductive objects during operation.
