We previously explained the HSTX high-speed serial transmit interface of the Raspberry Pi RP2350 microcontroller was mostly useful for video outputs and display interfaces since it can only transmit, and not receive data. But Steve Markgraf found another use case for the HSTX interface – high-speed data acquisition – combining a Raspberry Pi Pico 2 board with the DVI Sock board for Pico and one of those cheap MS2130-based HDMI to USB 3.0 video capture dongles. He managed to stream out up to 75 MB/s of real-time data from an overclocked RP2350 to a host computer with a USB 3.0 port. The Adafruit Feather RP2350 HSTX board should also work, but also not been tested. Steve’s “hsdaoh-rp2350” data acquisition over HDMI firmware is based on the dvi_out_hstx_encoder example from Raspberry Pi using the HSTX interface for DVI output and code by Shuichi Takano implementing the HDMI data island encoding required […]
CYOBot v2 ESP32-S3-based open-source modular robotics platform supports up to 16 servos (Crowdfunding)
Create Your Own Bot (CYOBot) v2 is an open-source, modular robotics platform for students, educators, hobbyists, and future engineers based on the ESP32-S3 microcontroller and featuring up to 16 servo motors for complex control. The CYOBot v2 is a follow-up to the previous quadrupedal robotic platform from the same company. It adds new features such as a modular design, an upgrade to the ESP32-S3 chip, more motor channels, and an expansion block with more peripherals. It also supports integrating AI systems, such as ChatGPT, for added functionality. The CYOBot supports up to three configurations via the CYOBrain — which powers the robotics platform and controls the servo motors — and separate 3D-printed components. The CYOBot Crawler is a four-legged robot powered by eight 180-degree servo motors. The CYOBot Wheeler form factor features four 360-degree motors linked to wheels at the end of each leg and is essentially a hybrid between […]
STMicro STSPIN32G0 3-phase motor controllers support up to 24V for portable appliances, up to 600V for industrial automation
STMicro STSPIN32G0 is a new series of advanced 3-phase motor controllers with variable voltage ranging from 45V to 600V that extend STMicro’s portfolio of devices with an integrated MCU and motor driver. The new series combines a triple-half bridge gate driver with the Arm Cortex-M0+-based STM32G0 microcontroller and is capable of handling six-step and field-oriented control (FOC) algorithms. The integrated design of the STSPIN32G0 series offers cost-savings and “significant BOM area reduction without compromising performance and robustness.” There are two main versions of the STSPIN32G0 series, low-voltage and high-voltage. The low-voltage 3-phase motor controllers include a voltage regulator, one or three shunts, and a gate driver rated at 45V and up to 0.6A. They are mainly targeted at home appliances, power tools, and drones. The high-voltage versions can handle either 250V or 600V, making them suitable for industrial inverters and fans. They are targeted at home appliances, air conditioners, home […]

LG Display’s 12-inch stretchable screen can extend by up to 50%
A new category of devices – the stretchables – may soon be upon us, as after writing about Murata stretchable PCBs for medical applications a few days ago, I’ve now come across LG’s latest stretchable display that can be extended from its original 12-inch size up to 18 inches. It’s the second stretchable display showcased by the Korean company, as the first prototype was unveiled in 2022 with an elongation rate of just 20%. The new display extends that to 50% and delivers a high resolution of 100ppi (pixels per inch) and full red, green, and blue (RGB) color (probably at its original size). LG Display further explains that their engineers have applied a number of new technologies “such as improving the properties of a special silicon material substrate used in contact lenses and developing a new wiring design structure to improve the panel’s stretchability and flexibility”. Durability was also […]
Signaloid C0-microSD is an iCE40UP5K FPGA SoM in the microSD card form factor (Crowdfunding)
Cambridge-based hardware and cloud computing company, Signaloid has begun crowdfunding for the C0-microSD – a tiny, programmable iCE40UP5K FPGA system-on-module (SoM) in a microSD card form factor. It comes preloaded with a RISC-V softcore and users can also load custom FPGA designs onto the board. Part of the Signaloid C0-microSD’s unique appeal is its SD card form factor, which allows it to fit in unused full SD or microSD slots. This allows the implementation of FPGA-based hardware acceleration in systems without traditional expansion interfaces like PCIe M.2 slots. It can also be interfaced with as a standard SD block device and used to bring hardware-accelerated data processing to existing industrial automation, manufacturing, and robotics systems. The iCE40UP5K FPGA SoM has two main use cases: a hot-pluggable FPGA module or a hot-pluggable RISC-V co-processor module. The SD interface allows you to load custom FPGA bitstreams and applications onto the module from […]
M5Stack releases AX630C-powered offline “Module LLM” for local smart home and AI applications
The M5Stack Module LLM is yet another box-shaped device from the company that provides artificially intelligent control without internet access. It is described as an “integrated offline Large Language Model (LLM) inference module” which can be used to implement local LLM-based solutions in smart homes, voice assistants, and industrial control. Module LLM is powered by the AX630C SoC, equipped with 4GB LPDDR4 memory, 32GB storage, and a 3.2 TOPS (INT8) or 12.8 TOPS (INT4) NPU. M5Stack says the main chip has an average runtime power consumption of 1.5W, making it suitable for long-term operation. It has a built-in microphone, speaker, microSD card slot, and USB OTG. The USB port can connect peripherals such as cameras and debuggers, and the microSD card slot supports cold and hot firmware updates. The M5Stack Module LLM joins the list of other offline, on-device LLM-based solutions, such as the SenseCAP Watcher, Useful Sensors’ AI in […]
Murata unveils stretchable PCB technology for medical and bio-sensing applications
Many PCB vendors now provide flexible PCB manufacturing services, but Murata goes further with stretchable PCB technology that’s not only bendable but can be twisted and stretched to better fit on the body for bio-sensing and medical applications even on parts such as an elbow. Traditional bio-monitoring sensors have some limitations. For example, they can become unstuck when the body moves, damage the delicate skin of infants and the elderly, data may be distorted due to body movement, and Murata explains “there is a risk of a decline in insulation and the occurrence of ion migration when using a thermoplastic polyurethane elastomer (TPU), known as a stretchable base material, in a high humidity environment”. The company’s stretchable printed circuits ((SPC) are supposed to solve or at least mitigate all those issues. The technology is under development, but Murata still shared some highlights of the technology: Stretchable electrode printing in compliance […]
