NextPCB Officially Launches Rev 0 PCBA — An Automated, No-Touch Prototype Assembly Service Built for Speed and Predictability (Sponsored)

NextPCB Rev 0 PCBA manufacturing service

NextPCB today announced the official launch of Rev 0 PCBA, a fully automated, no-touch prototype assembly workflow engineered to eliminate traditional manufacturing obstacles and dramatically accelerate early hardware development. Rev 0 PCBA introduces a new era of rapid prototyping by automating the entire front‑end workflow – from file upload to assembly – without engineering queries, manual intervention, or unpredictable delays or costs. “Rev 0 PCBA was born from countless conversations with engineers. The EQ email loop kept coming up as the biggest momentum‑killer, so we built a workflow that removes it entirely. By integrating DFM directly into the process, we’ve created a no‑touch path from screen to factory floor — no delays, no back‑and‑forth, just clean, confident verified builds. And with our new Jiangmen Smart Manufacturing Base, we can deliver those builds with ultra-fast, reliable production.” said Ivy Li, head of international business development at NextPCB. Rev 0 PCBA leverages NextPCB’s award‑winning DFM/DFA engine […]

PENOX WristBuds – A Bluetooth 6.0 smartwatch with integrated TWS earbuds (Crowdfunding)

WristBuds 2 in 1 Smartwatch with ENC Earbuds

PENOX WristBuds is a 2-in-1 rugged Bluetooth 6.0 smartwatch with integrated TWS earbuds, eliminating the need for a separate charging case. Designed for outdoor enthusiasts and the “zero-clutter mobility” market. The watch is built around a Bluetrum AB5681G RISC-V smartwatch MCU managing both the smartwatch interface and audio synchronization. The device sports a large 2.1-inch IPS display with a 320×390 resolution and is housed in a CNC-machined zinc alloy body. But what’s interesting about this is its mechanical, spring-loaded “Pop & Snap” design that houses the TWS earbuds inside the watch, and eliminates the need for a separate charging case. PENOX WristBuds specifications: MCU – Bluetooth AB5681G CPU – 32-bit RISC-V CPU @ up to 140 MHz Memory – TBC (not mentioned at all in the MCU datasheet) Storage – 128Mbit integrated NOR Flash Display & Graphics – SPI/QSPI display engine with HW acceleration (DMA, rotation, scaling, blending) Audio – […]

M5Stack PaperColor ESP32-S3 devkit features 4-inch E Ink Spectra 6 color display

M5Stack PaperColor, or M5Paper Color, is an ESP32-S3 development kit with a 4-inch E Ink Spectra 6 full-color display with a resolution of 600×400, designed to offer both low power consumption and high visibility under strong lights. While the color ePaper display is the start of the show, the devkit also features a microSD card slot for storage, a microphone with echo cancellation, a 1W speaker, a temperature & humidity sensor, a few buttons, two RGB LEDs, and an IR transmitter, but no GPIO expansion connectors. With regards to power, a 1250 mAh battery is included, rechargeable through the device’s USB Type-C port.

Start9 RISC-V Router features SpacemiT K1 SoC, runs StartWRT OpenWrt fork (Crowdfunding)

Start9’s “RISC-V Router” is powered by a SpacemiT K1 octa-core RISC-V processor paired with 4GB RAM and 16GB eMMC flash, and offers dual GbE networking, as well as an AsiaRF AW7915-NP1 WiFi 6 4T4R module enabling up to 2401 Mbps combined data link. It’s not exactly a high-end router, but Start9 claims it is the “most open router on the market” thanks to its RISC-V processor, OpenSBI open-source boot stack, and StartWrt operating system, a fork of OpenWrt. Start9 router specifications: SoC – SpacemiT K1 CPU – 8-core X60 RISC-V processor with single-core performance equivalent to about 1.3x the performance of an Arm Cortex-A55 GPU – Imagination IMG BXE-2-32 with support for OpenCL 3.0, OpenGL ES3.2, Vulkan 1.2 VPU – H.265, H.264, VP9, VP8 4K encoding/encoding NPU – 2.0 TOPS AI accelerator System Memory – 4GB LPDDR4 Storage 16GB eMMC flash MicroSD card slot Networking 2x Gigabit Ethernet RJ45 ports […]

Yocto Project 6.0 “Wrynose” released with Linux 6.18 LTS

The Yocto Project 6.0, codenamed “Wrynose”, has just been released with Linux 6.18 LTS, about two years after Yocto Project 5.0 “Scarthgap” release with Linux 6.6 LTS. Over 240 contributors submitted over 4000 commits since the previous Yocto 5.3 “Whinlatter” minor release of the popular framework used to create custom embedded Linux distributions. Yocto Wrynose is a Long Term Support (LTS) release, which will be supported until at least April 2030. The project’s developers especially highlight these 4 years of support, improved SBOM and CVE tracking features, and more secure defaults to ease compliance with the upcoming EU Cyber Resilience Act (CRA). Yocto Project 6.0 highlights: Linux kernel 6.18 LTS Toolchain updates: GCC 15.2, glibc 2.43, LLVM 22.1, Go 1.26, and Rust 1.94. New bitbake-setup tool to fetch layers and setup build directories. Support for BitBake configuration fragments, which can be managed with the new bitbake-config-build command. This enables better […]

PortaRF single board SDR mixes HackRF One and PortaPack H4M hardware, adds AI voice control

Designed by OpenSourceSDRLab, the PortaRF is an open-source software-defined radio (SDR) that integrates HackRF One and the PortaPack H4M into a single device. It’s a standalone device that supports transmitting and receiving radio signals from 1 MHz to 6 GHz. Traditionally, a portable HackRF setup meant stacking a PortaPack on top of the main board. PortaRF replaces this with a single PCB, making it more compact, easier to use, and with improved signal quality. It also adds a larger display, more flash, and a bigger battery. PortaRF specifications: MCU – NXP LPC432 dual core ARM Cortex M4/M0 (LPC4320FBD144) microcontroller CPLD Xilinx XC2C64A CoolRunner-II AGM AG256SL100 RF ICs MAX2837 – 2.3GHz to 2.7GHz Wireless Broadband RF Transceiver RFFC5072 – Wideband Synthesizer/VCO with Integrated 30MHz to 6 GHz Mixer Frequency range – 1 MHz to 6 GHz (Transmit and Receive) Storage 2MB SPI Flash (W25Q16DV) provides more space for the Mayhem firmware MicroSD card slot […]

Clawdmeter – A DIY ESP32-S3 desk dashboard for Claude Code token usage monitoring

Clawdmeter is a DIY ESP32-S3-powered desk dashboard that displays Claude Code token usage on a 2.16-inch AMOLED screen so you know when you’re about to reach the limits in real time. It’s mostly a firmware project since it relies on off-the-shelf hardware (Waveshare ESP32-S3-Touch-AMOLED-2.16). It leverages the LVGL library for its graphics user interface, the NimBLE stack for Bluetooth LE (BLE) communication, and also functions as a HID keyboard for shortcuts using the buttons from the unit. We previously covered Waveshare ESP32-S3-Touch-AMOLED-1.8 with a 1.8-inch display, but never the 2.16-inch variant, so let’s have a quick look at the hardware first. ESP32-S3-Touch-AMOLED-2.16 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Memory – 512KB RAM, 8MB PSRAM ROM – 384KB Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE Storage 16MB NOR flash MicroSD card slot […]

DEEPX DX-AIPlayer N97 mini PC combines Intel N97 SoC and 25 TOPS DX-M1 AI accelerator

DEEPX has just launched the DX-AIPlayer, an ultra-compact edge AI mini PC with an Intel Processor “Alder Lake-N” N97 SoC and the company’s DX-M1 M.2 AI accelerator module. The system is designed for real-time vision AI applications in robotics, smart cities, and factory automation. We’ve seen plenty of Alder Lake-N mini PCs like the Jetway B420UADN1, the Avalue EPC-ASL, the AAEON UP 710S, and various others, but the DX-AIPlayer N97 is different as it integrates the DX-M1 module via an M.2 2280 M-Key (PCIe Gen 3 x4) slot. The NPU delivers up to 25 TOPS of INT8 AI performance while consuming only 1 to 5 Watts of power, and features 4GB of dedicated LPDDR5 memory to handle larger workloads and multi-model execution without bottlenecking the host system’s RAM. DEEPX DX-AIPlayer N97 specifications: SoC – Intel Processor N97 quad-core processor up to 3.6 GHz with 6MB cache, 24 EU Intel UHD graphics […]
