TTGO T-Motion USB adapter offers LoRa and GPS for under $30

USB adapters are one of the easiest ways to add new features to existing hardware, and if you’d like to add LoRa connectivity and GPS tracking to any device or board with a USB board TTGO T-Motion USB adapter offers just that. Manufactured by LilyGO, the USB dongle is based on AcSiP S76G system-in-package that integrates an STM32 MCU with a Semtech SX1276 LoRa transceiver and GPS into a single. The GPS antenna is placed on the board inside the enclosure, while the external LoRa antenna is connected through an SMA connector. TTGO T-motion specifications: SiP – AcSiP S76G system-in-package with STMicro STM32L073x Arm Cortex M0+ MCU with up to 192 KB of Flash memory and 20 KB of RAM, Semtech SX1276 supporting global 868 MHz or 915 MHz ISM-Bands, Sony CXD5603GF GNSS receiver. Antenna Internal GPS antenna External LoRa antenna Host interface – USB 2.0 male port Misc – […]

Linux 5.13 Release – Notable changes, Arm, MIPS and RISC-V architectures

Linus Torvalds has just announced the release of Linux 5.13: So we had quite the calm week since rc7, and I see no reason to delay 5.13. The shortlog for the week is tiny, with just 88 non-merge commits (and a few of those are just reverts). It’s a fairly random mix of fixes, and being so small I’d just suggest people scan the appended shortlog for what happened. Of course, if the last week was small and calm, 5.13 overall is actually fairly large. In fact, it’s one of the bigger 5.x releases, with over 16k commits (over 17k if you count merges), from over 2k developers. But it’s a “big all over” kind of thing, not something particular that stands out as particularly unusual. Some of the extra size might just be because 5.12 had that extra rc week. And with 5.13 out the door, that obviously means […]

Ubuntu 20.04/21.04 64-bit RISC-V released for QEMU, HiFive boards

Let’s a lot of excitement around RISC-V open architecture, but a lot of work still needs to be done to bring the ecosystem to level with Arm or x86 architecture from the silicon to the software. Progress is made step-by-step and one of these steps is Canonical released Ubuntu 64-bit RISC-V (RISCV64) images for some of SiFive HiFive boards, as well as QEMU open-source emulator. Specifically, Canonical released an Ubuntu 20.04.2 LTS image for HiFive Unleashed & QEMU, and an Ubuntu 21.04 image for HiFive Unleashed, HiFive Unmatched, and QEMU. Note those are only server images, and there’s no desktop image yet like for Ubuntu 21.04 on Raspberry Pi 2/3/4. It’s been possible to run RISC-V Linux in QEMU for at least three years, but when I tried it was a minimal system based on Busybox, so let’s try again with Ubuntu 21.04 following the instructions provided on Discourse. I […]

TPM 2.0 modules quadruple in price, run out of stock following Windows 11 announcement

Microsoft announced Windows 11 with new system requirements that include having hardware with a TPM 2.0 chip. Yesterday, we noted that could be an issue, as not all computers, laptops, and tablets may come with a Trusted Platform Module (TPM), especially if version 2.0 is required. Microsoft explains it’s for a good reason, name improved security, but the requirement has already had an impact on the market, even though Windows 11 is not officially available just yet, as TPM 2.0 modules have quadrupled in price according to a Tweet from Shen Ye, senior director, global head of hardware products for HTC. Note that while the bottom scale shows dates, it only shows dates when the price changes and the price was indeed $24.90 before Microsoft’s announcement, and gradually went up to $99.90 within 12 hours. At the time of writing, that module is out of stock on Amazon. Shen further […]

Windows 11 announced with widgets, Android apps support, new system requirements

As expected, Microsoft has formally announced Windows 11 operating system that’s basically Windows 10 with a new look, and some extra features such as Snap Layouts, Snap Groups, and Desktops to further improve the multitasking experience. Snap Layouts and Snap Groups will allow you to select pre-defined layouts to quickly arrange windows as you see fit, and you can define multiple “Desktops” for work, gaming, or school, etc… Other changes include Chat from Microsoft Teams integrated into the taskbar, new gaming features such as DirectX 12 Ultimate, Direct Storage for faster loading, or Auto HDR, a new Microsoft Store with support for Android apps through the Amazon Appstore, and AI-powered widgets to display useful information like calendar, weather, news, stock quotes, etc… There are also features that have become deprecated or pushed to the wayside with, for example, Cortana not used anymore during installation and not pinned to the taskbar, […]

RasPad 3 Review – Part 1: Raspberry Pi 4 “tablet” specs, unboxing and assembly

RasPad tablet kit for Raspberry Pi 3B+ and other SBC’s was introduced in 2018, but Sunfounder has recently introduced an update, RasPad 3 that supports the more powerful Raspberry Pi 4 SBC. After seeing my review of CrowPi2 Raspberry Pi 4 education laptop, the company asked me whether I’d be interested in reviewing Raspad 3 as well. So here we are, and I’ve received a sample of the tablet kit. As usual, I’ll do a two-part review, with unboxing and assembly of the kit. Since I previously missed the RasPad 3 announcement, I’ll start by listing some of the specifications. RasPad 3 specifications Compatible board – Raspberry Pi 4B with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8G RAM Storage – MicroSD card socket Display – 10.1-inch touchscreen IPS display with 1280×800 resolution, 10-point touch Video Output – Full-size HDMI output Audio – 3.5 mm headphone jack, stereo speaker Connectivity […]

USB Type-C Specification 2.1 allows up to 240W Extended Power Range (EPR)

Many devices have switched from a Micro USB port or a power barrel jack to the USB-C port in recent years, as the latter allows for higher currents, and up to 100W power input in USB PD (Power Delivery) compliant systems. While 100W will be more than enough for most devices, more power-hungry devices or systems still need a power brick, for example, gaming laptops and mobile workstations. But the USB Type-C specification 2.1 aims to change that by upping the maximum power to 240W. As noted by Benson Leung in a Reddit Thread the part of the specification that handles the 240W power is the EPR (“Extended Power Range”) that defines requirements for cables, chargers, and devices: 3.11 Extended Power Range (EPR) Cables 3.11.1 Electrical Requirements Extended Power Range cables have additional requirements to assure that these cables can deliver the full defined voltage and current range for USB […]

Snapdragon QC710 Developer Kit targets Windows 10 on Arm app development

In order to encourage developers to port their apps to Windows 10 on Arm, Qualcomm and Microsoft have announced the Snapdragon Developer Kit based on a Snapdragon Compute platform and aiming to provide a cost-efficient platform that will be less costly than a laptop. The development kit looks like a mini PC, and while the full specs have not been announced, it could well be powered by the just-announced Snapdragon 7c Gen 2 processor, itself a cheaper version of Snapdragon 7c. Qualcomm did not share photos of all the ports from the developer kit, but the photos we’ve got come with “QC710” file name, and reveal a power button on the top, an LED on one corner, two USB ports, a MicroSD card slot, and a SIM card socket. I’d assume at least one HDMI or DisplayPort at the back, and possibly an Ethernet port, but we just don’t know […]
