Raspberry Pi Compute Module 4S SO-DIMM module is powered by Broadcom BCM2711 SoC

Raspberry Pi Compute Module 4S

The Raspberry Pi Compute Module 4S is an upcoming system-on-module based on the same Broadcom BCM2711 quad-core Cortex-A72 processor found in Raspberry Pi Compute Module 4, but using the same SO-DIMM connector as found in earlier Raspberry Pi Compute Module boards, instead of the new board-to-board connectors. The Raspberry Pi Compute Module 4S is not launched yet, but we discovered it will be used on Revolution Pi S and SE series DIN-rail industrial computers via a tweet from Jeff Geerling and his post on Raspberry Pi forums. Apart from the faster processor and support for 4K video output, The Raspberry Pi Compute Module 4S is quite similar to the Raspberry Pi Compute Module 3+. Memory bandwidth might be a little better with the LPDDR4 memory too (TBC), but all the rest looks the same. The main advantage of the new Raspberry Pi CM4S module is compatibility with older SO-DIMM carrier […]

Eben Upton expands on Raspberry Pi shortage

Raspberry Pi Shortage

As you may have noticed, Raspberry Pi boards may get hard to get and/or be sold at excessive prices by some resellers. Eben Upton explains the reasons behind the Raspberry Pi Shortage and provides some recommendations to work around the shortage and high prices. Raspberry Pi Trading is still manufacturing around 500,000 Raspberry Pi boards or modules per month despite the global semiconductors shortage, and the issue they face is more of a demand shock than a supply shock with demand for Raspberry Pi products having increased sharply from the start of 2021 and remains unabated as the supply chain can not handle that extra demand at this time. That means distributors have backlogs in almost all products, and it takes time for customers to get their orders. Bots are also involved in making automatic purchases as soon as stock becomes available often in order to resell those boards at […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.17 changelog

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]

CM4-IO-POE-4G-Box – A Raspberry Pi Compute Module 4 box for industrial IoT applications

CM4-IO-PoE-4G-Box

While the Raspberry Pi Compute Module 4 is basically unobtanium, companies keep introducing products based on the Arm system-on-module, and Waveshare CM4-IO-POE-4G-Box is a complete system designed for industrial IoT applications with CAN Bus, RS232 and RS485 interfaces, Ethernet with PoE support, plus optional support for 2G to 5G cellular connectivity. The CM4-IO-POE-4G-Box is based on the “Compute Module 4 PoE 4G” carrier board which itself appears to be an update to the company’s earlier “Compute Module PoE 4G” carrier board for the Raspberry Pi CM3 module. CM4-IO-POE-4G-Box / Compute Module 4 PoE 4GB board specifications: Support SoM – All variants of Raspberry Pi Compute Module 4 Storage – MicroSD card socket used for Raspberry Pi Compute Module 4 Lite (without eMMC) Display 2x HDMI ports up to 4Kp30 (I suppose even 4Kp60) 2x 15-pin MIPI DSI connectors + openings in the enclosure for flat cables Camera – 2x internal […]

Pockit modular Linux computer gets a Raspberry Pi CM4 upgrade

Pockit modular computer

We first wrote about the Pockit modular Linux computer with hot-plugging magnetic blocks about a year ago. The system was based on a STM32+ESP32 mainboard with a socket for an optional Raspberry Pi Compute Module 3 and included magnets and electrical contacts to snap and hot-plug modules/blocks while the computer is running. The developer (Anil Reddy) has made good progress with the project and added the option to use a Raspberry Pi CM4 with Pockit (provided you can find one) to improve performance, for example for computer vision. Other changes include support for AI accelerators, an improved dashboard, home automation integration, and more. Pockit now supports over 80 feature BLOCKS ranging from a rotary encoder to a microSD card reader to various camera types, an HDMI block, AI accelerators, and so on. All of which can be magnetically snapped while the computer is running, and automatically detected in the dashboard. […]
