Farnell launches Raspberry Pi Compute Module 4
The CM4 is accompanied by two new accessories, the Compute Module 4 I/O (CM4IO) Board and the Compute Module 4 Antenna Kit.
CM4 is a System on Module (SoM) that provides a larger range of connectivity and memory options that previous Rasperry Pi compute modules. Key features of the module include greater power efficiency, PCle support and a wide selection of multimedia interfaces. CM4 is ideal for AI, the IoT and a wide range of home and industrial automation applications.
CM4 is based on the Raspberry Pi Model 4B single-board computer. It comes in a smaller form factor that includes new interfaces such as dual HDMI, PCIe and Gigabit Ethernet. Access to the processor interfaces and GPIO pins comes through dual 100 pin high density connectors. The SoM is available with different eMMC flash and DRAM density options, and also features optional dual-band wireless connectivity. A “lite” variant is also available that comes without the eMMC fitted.
CM4 features include:
• A Broadcom BCM2711 quad-core ARM Cortex-A72 64-bit processor clocked at 1.5GHz, offering industry-leading performance and power efficiency.
• 1GB to 8GB of LPDDR4-3200 SDRAM and up to 32GB of eMMC Flash memory depending on the model.
• Hardware codec support for H.265 (up to 4kp60 decode) and H.264 (up to 1080p60 decode and 1080p30 encode).
• Optional fully certified radio module, supporting dual-band IEEE 802.11 b/g/n/ac wireless networking and Bluetooth 5.0.
The CM4IO Board simplifies the design of new products using the CM4. It can be used for evaluation and prototyping, or to serve as a reference design to interface external devices to the CM4 and embedded directly into end products. The CM4IO Board can be used with the complete range of CM4 modules and features:
• Gigabit Ethernet connectivity with PoE support (requires separate Raspberry Pi PoE HAT)
• Two full-size HDMI connectors
• Two USB 2 sockets, with a header for two more sockets
• A micro-USB socket for updating the CM4 and a micro SD Card socket for CM4Lite modules
• A PCIe Gen 2 x1 socket
The Compute Module Antenna Kit has an external antenna that is pre-certified for use with the CM4. It is supplied with a bulkhead fixture and a cable with a U.FL connector.
Lee Turner, Global Head of Semiconductors and SBC at Farnell said: “Ease of use is key to our customers: with its extensive documentation, mature software stack, and vast community the Raspberry Pi Compute Module series has always been a very popular product for embedded engineers. This new version of the Compute Module offers greater performance and connectivity as well as improved energy efficiency, and is simpler than ever to incorporate into products. With dual HDMI, PCI Express, a choice of RAM and eMMC memory options, and a dual-band option, design engineers can develop a broader range of applications, bringing their products to market faster than ever before.”
Eben Upton, Chief Executive at Raspberry Pi Trading, said: “Since 2014, the Compute Module line has become an increasingly important part of Raspberry Pi’s offering, allowing our customers to leverage the cost, performance and stability of the Raspberry Pi platform in their own products, with their own form factors. Farnell have been at the heart of the Compute Module program, investing to ensure our customers can access the inventory they need when they need it, and providing unparalleled support through the element14 Community. Compute Module 4 extends the range with the power of Raspberry Pi 4, adding RAM density variants, optional wireless connectivity and an even wider range of interfacing options. We’re excited to see what people build with CM4 platform.”
