Raspberry Pi Compute Module 4 8GB RAM, 32GB eMMC, WIFI

Specifications

• Processor: Broadcom BCM2711 Quad-Core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
• Memory (RAM): 8GB LPDDR4-3200 SDRAM
• Storage: 32GB eMMC Flash (on-board industrial storage)

      Connectivity:

• Dual-band 2.4GHz and 5.0GHz IEEE 802.11 b/g/n/ac Wireless LAN
• Bluetooth 5.0, BLE
• Onboard U.FL antenna connector (for external antenna usage)

• Interface: Dual 100-pin high-density Hirose connectors
• Video: Dual HDMI interface (up to 4Kp60 supported)
• Multimedia: H.265 (4Kp60 decode), H.264 (1080p60 decode, 1080p30 encode)
• PCIe: 1x PCIe Gen 2.0 lane (accessible via carrier board)
• Input Power: 5V DC via connector

Applications

• Industrial IoT Gateways: Compact, reliable edge processing with onboard WiFi for telemetry.
• Digital Signage: Dual 4K output capabilities in a slim profile for mounting behind displays.
• Custom Handheld Consoles: High performance gaming emulation in a custom PCB footprint.
• Computer Vision: utilize the CSI camera ports for high-speed image processing on the edge.

Project Evolution

• Mastered This:  Raspberry Pi 4 Model B. You've built a media center or a basic server but hit the physical limits of the credit-card-sized board.
• The Upgrade: The Compute Module 4 strips away the Ethernet jacks and USB towers. It exposes the raw PCIe lanes, allowing you to connect high-speed NVMe SSDs, custom AI accelerators, or multiple gigabit Ethernet ports directly to the CPU.
• Effort Level: Advanced. Requires a Carrier Board (IO Board) to function. You cannot power this solely via USB like a standard Pi.

Virtual Technician & Setup Guide

• ⚠️ Connection Warning: The CM4 uses two 100-pin high-density connectors. These are NOT compatible with the older SO-DIMM style slots from CM3/CM3+. You need a CM4-specific carrier board.
• WiFi Antenna: This model includes an onboard PCB antenna. However, if you place it inside a metal enclosure, you must connect an external antenna to the U.FL connector.
• Flashing the eMMC: To flash the OS onto the 32GB eMMC, you need the CM4 IO Board (or similar) and must jumper the "nRPiBOOT" pins to mount the storage as a drive on your PC.

Package Includes: 

• 1x Raspberry Pi Compute Module 4 8GB RAM, 32GB eMMC, WIFI

Frequently Asked Questions (FAQ)

• Does this CM4 version come with WiFi?
  Yes, this model includes Dual-Band WiFi and Bluetooth 5.0.
• Can I use a microSD card with this module?
  No, this version has 32GB eMMC storage. The microSD interface on carrier boards is usually disabled when eMMC is present.
• Do I need an external antenna?
  It works with the onboard PCB antenna, but an external antenna (via U.FL) provides better range, especially in enclosures.
• Is this compatible with Raspberry Pi 3 CM3 carrier boards?
  No, the form factor and connectors (Hirose vs. SODIMM) are completely different.
• How do I install the Operating System?
  You must use a carrier board with a USB slave port and the rpiboot utility to flash the internal eMMC.
• Can I run Windows 10/11 IoT on this?
  Yes, the ARM architecture supports Windows on ARM, though Raspberry Pi OS (Linux) is recommended for stability.
• What is the maximum operating temperature?
  It is rated for -20°C to +85°C, but a heatsink is recommended for sustained performance.
• Does it support NVMe SSDs?
  Yes, it exposes a PCIe Gen 2.0 x1 lane, allowing NVMe SSD connection via a compatible carrier board.
• How much RAM does this unit have?
  This specific SKU comes with 8GB of LPDDR4 RAM.
• Can I use the official Raspberry Pi Camera Module?
  Yes, provided your carrier board has the appropriate CSI connectors.
• What is the input voltage required?
  The module itself requires 5V. Your carrier board usually handles the power regulation.
• Is the 32GB storage expandable?
  The internal eMMC is fixed. You can add extra storage via USB or PCIe (NVMe/SATA) depending on your carrier board.
• Does it support dual monitors?
  Yes, it supports dual HDMI output up to 4K resolution.
• Is this good for a Plex server?
  Yes, the 8GB RAM and hardware transcoding support make it excellent for a compact media server.
• What happens if I plug it in backwards?
  The connectors are keyed to prevent this, but forced misalignment can damage pins. Handle with care.
• Does it have an Ethernet port?
  The chip supports Gigabit Ethernet (PHY built-in), but the physical RJ45 port must be on your carrier board.
• Can I use GPIO pins directly?
  Not directly from the module; you access GPIOs through the carrier board's headers.
• Is a heatsink included?
  No, the module is sold bare. We sell compatible heatsinks separately.
• What is the warranty period?
  Standard manufacturer warranty against manufacturing defects applies.
• Is this the "Lite" version?
  No, "Lite" versions have no eMMC. This version has 32GB eMMC.
