The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory)

The New Model A+ replaced the Model A in November 2014. The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 Megabytes of RAM. This revision A+ board features four mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports. The design does not include a built-in hard disk or solid-state drive, instead relying on an microSD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.

The Raspberry Pi Compute Module 3 Lite (CM3L) is a DDR2-SODIMM-mechanically-compatible System on Module (SoM) containing processor, memory and supporting power circuitry. The module allows a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition the module has extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards opening up more options for the designer. The CM3L contains a BCM2837 processor (as used on the Raspberry Pi 3) and 1GB LPDDR2 RAM. The CM3L product is the same as CM3 except the eMMC Flash is not fitted, and the SD/eMMC interface pins are available for the user to connect their own SD/eMMC device. Note that the BCM2837 processor is an evolution of the BCM2835 processor (as used on the original Raspberry Pi and Raspberry Pi B+ models, as well as the first iteration of the Compute Module). The only real differences are that the BCM2837 can address more RAM (up to 1GB) and the ARM CPU complex has been upgraded from a single core ARM11 in BCM2835 to a Quad core Cortex A53 with dedicated 512KB L2 cache in BCM2837. All IO interfaces and peripherals stay the same and hence the two chips are largely software and hardware compatible. The pinout of the CM3L is identical to that of the original Compute Module (CM1). Apart from the CPU upgrade and increase in RAM the other significant hardware differences to be aware of are that CM3L has grown from 30mm to 31mm in height, the VBAT supply can now draw significantly more power under heavy CPU load, and the HDMI HPD N 1V8 (GPIO46 1V8 on CM1) and EMMC EN N 1V8 (GPIO47 1V8 on CM1) are now driven from an IO expander rather than the processor. If a designer of a CM1 product has a suitably specified VBAT, can accomodate the extra 1mm module height increase and has followed the design rules with respect to GPIO46 1V8 and GPIO47 1V8 then a CM3L should work fine in a board designed for a CM1.

Five years to the day since the launch of the Raspberry Pi (which sold a hundred thousand units in the first day), the Raspberry Pi Foundation has announced the Raspberry Pi Zero W, a new variant of Raspberry Pi Zero with wireless LAN and Bluetooth, priced at only $10. So what’s the story? In November 2015, the diminutive $5 entry-level Raspberry Pi, the Raspberry Pi Zero, was launched. This represented a fivefold reduction in cost over the original Model A: it was cheap enough that one was even stuck on the front cover of The MagPi, risking civil insurrection in newsagents up and down the land. Over the ensuing fifteen months, Zero grew a camera connector and found its way into everything from miniature arcade cabinets to electric skateboards. Many of these use cases need wireless connectivity. The homebrew “People in Space” indicator in the lobby at Pi Towers is a typical example, with an official wireless dongle hanging off the single USB port: users often end up adding a USB hub to allow them to connect a keyboard, a mouse and a network adapter, and this hub can easily cost more than the Zero itself. Zero W fixes this problem by integrating more functionality into the core product. It uses the same Cypress CYW43438 wireless chip as Raspberry Pi 3 Model B to provide 802.11n wireless LAN and Bluetooth 4.0 connectivity. Features: 1GHz, single-core CPU 512MB RAM Mini-HDMI port Micro-USB On-The-Go port Micro-USB power HAT-compatible 40-pin header Composite video and reset headers CSI camera connector 802.11n wireless LAN Bluetooth 4.0 The Zero W makes a better general-purpose computer because you’re less likely to need a hub: if you’re using Bluetooth peripherals you might well end up with nothing at all plugged into the USB port. And of course it’s a great platform for experimenting with IoT applications. Official case To accompany Raspberry Pi Zero W, we’ve been working with our friends at Kinneir Dufort and T-Zero to create an official injection-moulded case. This shares the same design language as the official case for the Raspberry Pi 3, and features three interchangeable lids: A blank one One with an aperture to let you access the GPIOs One with an aperture and mounting point for a camera The case set also includes a short camera adapter flexi, and a set of rubber feet to make sure your cased Zero or Zero W doesn’t slide off the desk.

The Compute Module 3 contains the guts of a Raspberry Pi 3 (the BCM2837 processor and 1GB RAM) as well as a 4GB eMMC Flash device (which is the equivalent of the SD card in the Pi). The Pi 3 has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU. This is all integrated on to a small 67.6mm x 31mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the Module itself. The Compute Module is available for purchase in single units, or in batches of hundreds or thousands. To get started designing a PCB to use the Module, we provide an open-source breakout board with a single Module in an affordable development kit. A lite version of the Compute Module 3 is also available. The CM3L brings the SD card interface to the Module pins so a user can wire this up to an eMMC or SD card of their choice.
