Rimer SBC is a Microchip SAMD51 Cortex-M4-based development board with a built-in LCD, keyboard, audio, and battery

The Rimer SBC is a development board based on a Microchip SAMD51 Cortex-M4 microcontroller and designed as a complete standalone playground with a built-in display, keyboard, audio input and output, a few I/Os, and a 60x20mm LiPo battery or an optional 18650 battery holder. It is specifically based on the Microchip ATMSAMD51J20A microcontroller, running at 120MHz with 1MB of flash memory and 256KB of RAM, and utilizes many of the peripherals available in the TQFP64 package. The board includes a 3.2-inch 320 x 240 IPS TFT LCD connected via high-speed SPI and a 40-key mechanical keyboard scanned via an I2C GPIO expander. It also features an amplified 700mW speaker output and buffered analog input and output is routed via the 3.5mm audio jack. The Rimer SBC’s standalone nature makes it suitable for on-the-go development, rapid prototyping, and educational purposes without the need for external hardware. The maker also plans to […]

OpenWrt 24.10 released with Linux 6.6, TLS 1.3 by default, and 1970 supported devices

OpenWrt 24.10 open-source lightweight Linux operating system for routers has just been released. It’s been upgraded to Linux 6.6 from Linux 5.15 in OpenWrt 2023.05, supports TLS 1.3 by default, improves support for WiFi 6 (802.11ax), and adds initial support for WiFi 7 (802.11be). After over one year of work since the release of OpenWrt 23.05, OpenWrt 24.10 adds over 5400 commits, and the total number of supported devices is now close to 2,000 at 1,970. It’s also the first stable release supporting OpenWrt One, the router directly designed by OpenWrt developers in collaboration with Banana Pi. OpenWrt 24.10 highlights: TLS 1.3 support in default images with MbedTLS 3.6 Activate POSIX Access Control Lists and file system security attributes for all file systems on devices with big flash sizes. Needed by docker. Note this is not enabled for all targets with the small_flash feature flag, including ath79/tiny, bcm47xx/legacy, lantiq/ase, lantiq/xrx200_legacy, […]

Linux 6.13 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.13 on the Linux Kernel Mailing List: So nothing horrible or unexpected happened last week, so I’ve tagged and pushed out the final 6.13 release. It’s mostly some final driver fixes (gpu and networking dominating – normal), with some doc updates too. And various little stuff all over. The shortlog is appended for people who want to see the details (and, as always, it’s just the shortlog for the last week, the full 6.13 log is obviously much too big). With this, the merge window for 6.14 will obviously open tomorrow. I already have two dozen pull requests pending – thank you, you know who you are. Linus Release about two months ago, Linux 6.12 – the new LTS version – brought us real-time “PREEMPT_RT” support that had always required out-of-tree patchsets until now, the completion of the EEVDF (Earliest Eligible […]

NXP MCX L14x and MCX L25x ultra-low-power Cortex-M33 MCUs target energy harvesting and battery-powered devices

NXP Semiconductors has launched the MCX L series of ultra-low-power Arm Cortex-M33 MCUs with the MCX L14x and MCX L25x SKUs. The new series offers similar peripherals as the rest of the MCX portfolio but uses a new “power management architecture that supports always-on, battery-powered applications” The MCX L series uses a dual domain architecture, with “real-time processing and ultra-low-power sensing functions in a single device.” The Arm Cortex-M33 core supports real-time processing functions while the Arm Cortex-M0+ core offers always-on operation in the ultra-low-power sense domain. The new microcontrollers reportedly use three times less power than their predecessors. The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control, industrial sensing, smoke and fire alarms, flow meters, smart appliances, and motion detectors. NXP MCX L14x and L25x specifications: CPU Main core: Arm Cortex-M33 microcontroller @ up to 96 MHz […]
