Electrocomponents plc, which trades as RS Components, has introduced the Raspberry Pi 3B, a version of the widely-known development board with 64bit support. It is based on the Broadcom BCM2837 SoC that includes a quad-core Cortex-A53 and is capable of 1.2GHz clock frequency. Cortex-A53 comply with the ARMv8A instruction set architecture and support both 64bit and 32bit addressing as well as providing backwards compatibility with the ARMv7 instruction set architecture, noted the company.

The single-board computer is the same credit-card size as previous models (85mm x 56mm x 17mm) but the processor is 50 per cent faster than the Pi 2B and 10 times faster than the original Raspberry Pi, stated the company. It is also an upgrade in that it has Bluetooth and wireless LAN connectivity integrated on the board making it more suitable for IoT development projects. The board is priced at about $35 plus local taxes.

The BCM2837 SoC runs alongside a BCM43438 combo chip that provides the 802.11b/g/n wireless LAN, Bluetooth Classic and Bluetooth Low Energy. BCM2837 also integrates a multimedia coprocessor that provides: 1.2Gpixels/s of fill rate, 1.8Gtexel/s of texturing rate; 29GFLOPs of shader compute throughput; OpenGL ES 1.1/2.0 support; 1080p60 hardware video decoding; 1080p30 hardware video encoding; and a hardware image sensor pipeline.

The Raspberry Pi 3 boots from a micro SD card and uses the New Out Of the Box Software (NOOBS) installation manager. The standard Raspbian operating system install comes bundled with a range of productivity applications and programming tools including Node-RED.

Most of the other I/O features are the same as previous versions of the Raspberry Pi therefore providing backwards compatibility. A Raspberry Pi 3 Compute Module I/O Board will also be available shortly from RS and Allied, enabling OEMs to develop their own Raspberry Pi 3 based solutions for many industrial applications.
