LILYGO T-Halow is an ESP32-S3 board with long-range WiFi HaLow, OV2640/OV5640 camera support

LILYGO T-Halow is an ESP32-S3 board equipped with a WiFi HaLow module with up to 1.2km range, a connector compatible with OV2640 and OV5640 camera modules, and an 18650 battery holder for power, as well as several GPIOs for expansion. We first wrote about 802.11ah low-power long-range WiFi standard operating at 900 MHz in 2014, but adoption has been slow and we’ve seen a few 802.11ah (WiFi HaLow) chips from Newracom and Morse Micro over the years, as well as USB adapters, a Raspberry Pi HAT, a mini PCIe card, gateways, and some development boards. All those rely on a Linux host, but the LILYGO T-Halow features a TX-AH WiFI HaLow module from Taixin Semiconductor that’s controller by AT commands through an ESP32-S3 or a micro USB port.

Linux 6.10 Release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]

The RPGA Feather dev board pairs RP2040 chip with a Lattice iCE40 FPGA for sensor fusion projects

Oak Development Technologies’ RPGA Feather board integrates the Raspberry Pi RP2040 microcontroller with the iCE5LP4K FPGA from Lattice Semiconductor into a compact development board in the Adafruit Feather form factor. The iCE5LP4K FPGA is an ultra-low-power chip in the iCE40 Ultra product family designed for mobile applications such as smartphones, tablets, and handhelds, while the Raspberry Pi RP2040 microcontroller makes it much easier to program the FPGA using CircuitPython. We have seen Oak Development Technologies’ earlier forays into FPGA Feather-compatible products such as the IcyBlue board (also based on iCE5LP4K FPGA) and the Lattice FeatherWing. RPGA Feather specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM FPGA – Lattice Semiconductor iCE5LP4K FPGA Logic Cells – 3,520 logic cells Memory 80 Kbits of embedded Block RAM (EBR) Distributed RAM: 640 bits 2x hardware I2C blocks and 2x hardware SPI blocks 26 I/Os for customized interfaces […]

Canonical releases Ubuntu 24.04 Server image for Milk-V Mars RISC-V SBC

Canonical has been releasing Ubuntu RISC-V images for SBCs and QEMU at least since 2021. The latest addition is an Ubuntu 24.04 Server image for the Mars credit-card-size SBC powered by StarFive JH7110 quad-core RISC-V SoC and designed by Shenzhen Milk-V Technology. That means we now have Ubuntu Server images for the QEMU emulator, AllWinner Nezha SBC, Microchip Polarfire SoC FPGA Icicle Kit, SiFive Unmatched mini-ITX motherboard, Sipeed LicheeRV Dock, StarFive VisionFive 2 SBC, and the Mars SBC. You’ll note there aren’t any Ubuntu Desktop images for now, because the GPU (if any) in RISC-V SoCs is not yet fully supported. Mars SBC specifications: SoC – StarFive JH7110 CPU – Quad-core RISC-V processor (RV64GC) at up to 1.5GHz GPU – Imagination BXE-4-32 GPU with support for OpenCL 1.2, OpenGL ES 3.2, Vulkan 1.2 VPU H.264 & H.265 4Kp60 decoding H.265 1080p30 encoding JPEG encoder / decoder System Memory – 1GB, […]

Linux 6.9 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.9 on LKML: So Thorsten is still reporting a few regression fixes that haven’t made it to me yet, but none of them look big or worrisome enough to delay the release for another week. We’ll have to backport them when they get resolved and hit upstream. So 6.9 is now out, and last week has looked quite stable (and the whole release has felt pretty normal). Below is the shortlog for the last week, with the changes mostly being dominated by some driver updates (gpu and networking being the big ones, but “big” is still pretty small, and there’s various other driver noise in there too). Outside of drivers, it’s some filesystem fixes (bcachefs still stands out, but ksmbd shows up too), some late selftest fixes, and some core networking fixes. And I now have a more powerful arm64 machine […]
