Raspberry Pi CM4 and CM4Lite Modules Launched for $25 and Up

We were expecting Raspberry Pi Compute Module 4 sometimes next year, but Raspberry Pi Trading Limited managed to launch the new module much earlier, as Raspberry Pi CM4 and CM4Lite modules have just been launched with a new, much more compact form factor incompatible with the earlier Compute Modules, an I/O board making use of the new features, and a choice of 32 models with variations in terms of memory and storage capacity, as well as the presence or lack thereof of a WiFi and Bluetooth wireless module. Raspberry Pi CM4 & CM4Lite Specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz with VideoCore VI GPU System Memory – 1, 2, 4, or 8GB LPDDR4-3200 SDRAM Storage – CM4: 4, 8, 16, or 32GB eMMC flash up to 100MB/s; CM4Lite: No storage device on module Networking Gigabit Ethernet transceiver Optional Wireless module with 802.11b/g/n/ac WiFi 5 and Bluetooth […]

Google Coral Dev Board mini SBC is now available for $100

Google Coral SBC was the first development board with Google Edge TPU. The AI accelerator was combined with an NXP i.MX 8M quad-core Arm Cortex-A53 processor and 1GB RAM to provide an all-in-all AI edge computing platform. It launched for $175, and now still retails for $160 which may not be affordable to students and hobbyists. Google announced a new model called Coral Dev Board Mini last January, and the good news is that the board is now available for pre-order for just under $100 on Seeed Studio with shipping scheduled to start by the end of the month. Coral Dev Board Mini specifications haven’t changed much since the original announcement, but we know a few more details: SoC – MediaTek MT8167S quad-core Arm Cortex-A35 processor @ 1.3 GHz with Imagination PowerVR GE8300 GPU AI/ML accelerator – Google Edge TPU coprocessor with up to 4 TOPS as part of Coral […]

Linux 5.9 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes […]
