Auspicious Machine modular handheld Linux PC with keyboard takes various Arm-based SoMs

The “Auspicious Machine” may look like a Blackberry phone, but it’s actually a handheld Linux PC with a built-in QWERTY keyboard and a 3.5-inch display that can be powered by a range of system-on-modules (SoM). The computer, whose name can also be translated as the “Auspicious Phone”, can be used as a Linux terminal with GPIO control, and for gaming with Linux distributions such as Batotera or RetroBat with the D-Pad and ABXY buttons found on the device. Auspicious Machine specifications: Supported SoMs Bigtreetech CB1 with Allwinner H616 quad-core Cortex-A53 processor and 1GB DDR4 Raspberry Pi CM4 with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB LPDDR4, up to 32GB eMMC flash Radxa CM3 with Rockchip RK3566 quad-core Cortex-A55 processor, up to 4GB LPDDR4, up to 64GB eMMC flash Banana Pi BPI-CM4 with Amlogic A311D octa-core Cortex-A73/A55 processor with 4GB LPDDR4 and 16GB eMMC flash Storage – MicroSD card socket […]

Raspberry Pi Debug Probe eases bare metal development for $12

The Raspberry Pi Debug Probe is a USB serial adapter based on the Raspberry Pi RP2040 microcontroller and designed to debug the Raspberry Pi Pico, third-party RP2040 boards, and pretty much any Arm board through SWD and/or UART interfaces. The main advantage over a typical USB-to-serial adapter is the presence of a Serial Wire Debug (SWD) bridge used for bare metal code development and debugging through tools such as OpenOCD. The Raspberry Pi Debug Probe specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB SPI flash (W25Q16JVUXIQ) Debug interfaces 3.3V Serial Wire Debug (SWD) 3-pin JST connector conforming to the Raspberry Pi Debug Connector Specification and compatible with the CMSIS-DAP standard 3.3V serial (UART) 3-pin JST connector USB – Micro USB port to connect to the host Misc BOOTSEL button for flashing firmware to the debug board Unpopulated 3-pin header with […]

ODROID-H3+ SBC review with “Unlimited Performance” mode and 2.5GbE Net Card

ODROID-H3+ Review with Net Card and Case Type 7

Hardkernel have added Intel Jasper Lake mini PCs to their ODROID-H series and they are known as the ODROID-H3 and ODROID-H3+. Like the discontinued ODROID-H2/H2+, this new series also supports the Net Card which will add four extra 2.5 gigabit Ethernet ports. Hardkernel kindly sent an ODROID-H3+ together with a selection of accessories for review and I’m going to look at the effect on performance when changing the Power Limit values in the UEFI (BIOS) together with the network performance of the Net Card. ODROID-H3+ hardware overview The ODROID-H3+ physically consists of a 110 x 110 mm (4.33 x 4.33-inch) motherboard complete with an Intel Pentium Silver Jasper Lake mobile N6005 processor which has 4 cores and 4 threads and can boost to 3.3 GHz and also includes Intel UHD Graphics. The processor, and nearly the entire motherboard, is covered by a large metal heat sink: The front of the […]

Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]

Ploopy – 3D printed open-source hardware headphones feature Raspberry Pi RP2040 MCU, TI PCM3060 24-bit DAC

I don’t think I’ve ever written about open-source hardware headphones. But that’s precisely what Ploopy offers with an amplifier based on a Raspberry Pi RP2040, a Texas Instruments PCM3060 24-bit DAC, and an amplifier circuit, as well as 3D printed parts and open-source firmware written in C. As we’ll see further below the project is reasonably well documented, and you can either build it from scratch, purchase a fully-assembled kit, or something in the middle. I suppose you could even do some knitting since woven covers are part of the build just in case making your own PCBs and 3D printing parts are not your things. The electronics are comprised of two boards: The Gould amplifier board with the Raspberry Pi RP2040, Texas Instruments PCM3060 24-bit 96/192 kHz DAC, and several TI OPA1688 audio operational amplifiers The Mazzoleni driver flex boards going into the left and right rings with a […]
