Newark, an Avnet Company, has launched the new Raspberry Pi Compute Module 4 (CM4), a faster and more powerful system on module (SoM) than previous models. The new CM4 from Raspberry Pi comes with two accessories, the Compute Module 4 I/O (CM4IO) board and the Compute Module 4 antenna kit.
Aimed at a range of embedded solutions, including home and industrial automation, along with artificial intelligence (AI) and IoT applications, the CM4 offers a greater range of connectivity and memory options. Key features include a small form-factor, greater power efficiency, PCle support, and a variety of multimedia interfaces. Newark estimates that 40 to 50 percent of Raspberry Pi boards are sold to industrial customers and OEMs.
The CM4 is based on the Raspberry Pi Model 4B single-board computer, with an updated form factor that supports new interfaces such as dual HDMI, PCIe and Gigabit Ethernet, in a reduced footprint. Access to the processor interfaces and GPIO pins is provided via dual 100-pin high-density connectors. Also new is the choice of different eMMC flash and DRAM density options and optional dual-band wireless connectivity. A “lite” variant is available without the eMMC for cost-sensitive applications.
Here are the key CM4 features:
- Processor:Broadcom BCM2711 quad-core ARM Cortex-A72 64-bit processor clocked at 1.5 GHz
- Memory:Options from 1 GB to 8 GB of LPDDR4-3200 SDRAM and up to 32 GB of eMMC Flash memory depending on the model
- Multimedia: Hardware codec support for H.265 (up to 4kp60 decode) and H.264 (up to 1080p60 decode and 1080p30 encode).
- Connectivity:Optional fully certified radio module, supporting dual-band IEEE 802.11 b/g/n/ac wireless networking and Bluetooth 5.0. An on-board electronic switch selects between an external or PCB antenna.
For the accessories, the CM4IO Board simplifies the development of new products using the CM4. It is suitable for the evaluation and prototyping of new products. It can be used as a reference design to interface external devices to the CM4 and also be embedded directly into end products. The Compute Module Antenna Kit is designed for CM4 variants with an on-board wireless module. It includes an external antenna that has been pre-certified for use with the CM4, easing compliance requirements. It is supplied with a bulkhead fixture and a cable with a U.FL connector.
The Raspberry Pi’s Compute Module 4 and accessories including the Compute Module 4 I/O Board and Compute Module 4 Antenna Kit are available from Newark in North America.
