Raspberry Pi Compute Module 4S REV2 1 GB RAM, 8 GB eMMC

Product detailed description

Raspberry Pi Compute Module 4S is a computing module featuring a quad-core Broadcom BCM2711 processor (the same as in the Raspberry Pi 4B) in a 200-pin SO-DIMM form factor, mechanically identical to the Compute Module 3 and 3+ modules. It is primarily intended for upgrading devices built on CM3/CM3+ – you can boost the CPU, graphics, and LPDDR4 memory performance to the level of Raspberry Pi 4 without the need to change the mechanical design. This variant features 1 GB RAM and 8 GB integrated eMMC memory for system boot, eliminating the need for a microSD card. The module does not feature Wi-Fi, Bluetooth, or Ethernet and requires a carrier board with a SO-DIMM slot and power supply for operation.

Specifications:

• Processor: Broadcom BCM2711, 4× ARM Cortex-A72 (ARMv8, 64-bit), 1.5 GHz
• Graphics: VideoCore VI, OpenGL ES 3.0
• Video:
  • Decoding: H.265 (HEVC) up to 4Kp60, H.264 up to 1080p60
  • Encoding: H.264 up to 1080p30
• RAM: 1 GB LPDDR4-3200 with ECC
• Storage: 8 GB eMMC
• Interface:
  • GPIO: 46 pins in two banks (GPIO0–27 and GPIO28–45), each bank optionally 1.8 V or 3.3 V logic
  • USB: 1× USB 2.0 High Speed (480 Mb/s)
  • HDMI: 1× HDMI 2.0, up to 4Kp60
  • Display: 1× MIPI DSI 2lane, 1× MIPI DSI 4lane
  • Camera: 1× MIPI CSI 2lane, 1× MIPI CSI 4lane
  • Composite video: 1× TV output (PAL/NTSC)
  • Buses on GPIO: I2C, SPI, UART, PWM
• Wireless connectivity: no (no Wi-Fi or Bluetooth)

• Power Supply:
  • VBAT: 2.5–5 V (main core power supply)
  • 3.3 V: 3.15–3.45 V
  • GPIO banks: 1.8 V or 3.3 V (depending on the selected logic)
  • 1.8 V: no longer required (can be connected for backward compatibility)
• Power consumption: approx. 1.5 W idle, approx. 7 W under load
• Connector: 200-pin SO-DIMM (JEDEC MO-224 dimensions, pinout is not electrically compatible with DDR2 memory)
• Compatibility: same form factor and dimensions as Raspberry Pi Compute Module 3 / 3+ (the BCM2711 chip is slightly taller than on the CM3)
• Operating system: Raspberry Pi OS and other distributions for Raspberry Pi 4
• Operating temperature: –20 °C to +85 °C
• Dimensions: 67.6 × 31 mm, 2× M2 mounting holes
• Availability in production: at least until January 2034

Package contents:

• 1× Raspberry Pi Compute Module 4S, 1 GB RAM, 8 GB eMMC

Note:

• To get it up and running, you will need a carrier board with a 200-pin SO-DIMM slot (e.g., the original board for CM3/CM3+ or your own design) and a corresponding power supply.
• For new designs, the manufacturer recommends Compute Module 4 / 5; the CM4S module is intended primarily as a replacement for CM3/CM3+ in existing devices.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
