WCH CH343 USB to serial chips support 1.8V to 5V IO voltage, 6 Mbps baud rate, custom VID/PID

WCH CH340 family of USB to serial chip is very popular, and often found on development boards for debugging/access to the serial console, but the company has now introduced the CH343 “Gen3” chip – just like CH9102F apparently – with a higher 6 Mbps baud rate, support for 1.8V, 2.5V, 3.3V, and 5V IO voltage, and the ability to request custom USB VID/PID numbers. Three variants exist with CH343P, CH343G, and CH343K with different packages: QFN16, SOP16, and ESSOP10 respectively. CH343P contains an EEPROM for easy customization, while CH343G and CH343K PID/VID can still be customized for larger orders. CH343 key features and specifications: Full-speed USB 2.0 device interface Hardware full-duplex serial UART interface with baud rate varies from 50bps to 6Mbps. Automatic identification and dynamic adaptation of common communication baud rate of 115200bps and below. Supports 5, 6, 7, or 8 data bits, as well as odd, even, space, […]

SkiffOS minimal Linux for embedded containers now supports Sipeed Nezha RISC-V board

SkiffOS minimal Cross-compiled Linux for embedded containers has just added support for Sipeed Nezha RISC-V single board computer, and work on the smaller Sipeed Lichee RV board has started. Wait… What is SkiffOS? I’ve never heard about it… That’s how the abstract from the white paper describes it: Embedded Linux processors are increasingly used for real-time computing tasks such as robotics and Internet of Things (IoT). These applications require robust and reproducible behavior from the host OS, commonly achieved through immutable firmware stored in read-only memory. SkiffOS addresses these requirements with a minimal cross-compiled GNU/Linux system optimized for hosting containerized distributions and applications, and a configuration layering system for the Buildroot embedded cross-compiler tool which automatically re-targets system configurations to any platform or device. This approach cleanly separates the hardware support from the applications. The host system and containers are independently upgraded and backed-up over-the-air (OTA). In other words, that’s […]

FOMO (Faster Objects, More Objects) enables real-time object detection on low-end embedded systems

FOMO used to stand for “Fear Of Missing Out” in my corner of the Internet, but Edge Impulse’s FOMO is completely different, as the “Faster Object, More Objects” model is designed to lower the footprint and improve the performance of object detection on resource-constrained embedded systems. The company says FOMO is 30x faster than MobileNet SSD and works on systems with less than 200K of RAM available. Edge Impulse explains the FOMO model provides a variant between basic image classification (e.g. is there a face in the image?) and more complex object detection (how many faces are in the image, if any, and where and what size are they?). That’s basically a simplified version of object detection where we’ll know the position of the objects in the image, but not their sizes. So instead of seeing the usual bounding box while the model is running, the face position will be […]

7-inch tablet with Intel Atom Z3735G processor sells for $55

Hardware platforms based on Atom Z3735G or Z3735F Bay Trail processors were all the rage in 2014-2016, as the processors were found in tablets, mini PCs, and single board computers sold at price points that provided alternatives to Arm platforms that may not be as well supported. But time has passed and those processors are really slow by today’s standard, so I was surprised to find out some companies were still selling products based on Bay Trail processors with the “MOMO7W” 7-inch tablet powered by an Intel Atom Z3735G quad-core processor, coupled with 1GB RAM and 16GB flash. MOMO7W tablet specifications: SoC – Intel Atom Z3735G quad-core Bay Trail processor @ up to 1.33 GHz / 1.83 GHz (Turbo) with Intel HD graphics; 2.2W SDP. Note: it’s indeed discontinued. Storage – 1GB SDRAM Storage – 16 GB eMMC flash, MicroSD card slot up to 32GB Display – 7-inch capacitive touch […]
