ST VL53L9CX direct Time-of-Flight 3D LiDAR supports 5cm to 9m range, 2.3K zones resolution

STMicroelectronics VL53L9CX, or VL53L9 for short, is the company’s first direct Time-of-Flight (dToF) 3D LiDAR all-in-one module. It offers a sensing range of 5 centimeters to 9 meters, a wide 72º field of view, a resolution of 2.3K zones, and up to 100 Hz frame rate. ST’s ToF sensors have gone a long way since we covered the VL53L0X sensor with a single zone and 2-meter range in 2017. Since then, the company has steadily improved its tiny ToF sensors with up to 64 zones and long range in recent sensors like the VL53L8CP. While the VL53L9CX is still tiny at 12.8 x 6.1 x 4.6 mm, it’s in a class of its own, acting like a mini 3D scanner with 2268 zones, and will be used for a range of applications in robotics, industrial automation, smart buildings, AR/VR, and healthcare. ST VL53L9CX 3D ToF camera module specifications: Multizone ranging […]

Ampisu is a compact pocket-sized USB lab power supply with SCPI and web control (Crowdfunding)

Ampisu Portable programmable lab power supply

The concept of a USB-C-based power supply is not new, and we have previously seen projects like XIAO Powerbread and Axiometa BrodBoost-C. As USB PD-based power adapters and power banks have become much cheaper, adjustable power supplies like the PocketPD and BenchVolt PD have come out. Both have their own limitation: the PocketPD has only a single output channel, thus hardly a lab power supply, and the BenchVolt PD is not quite compact enough to be considered pocket-friendly. This is where the Ampisu comes in. It’s a compact, pocket-friendly, and isolated three-output lab power supply designed to fit in a pocket and includes features of a typical full-sized power supply. It’s designed for low-power embedded work, field debugging, and automated test setups. Ampisu specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 125 MHz with 264KB SRAM Storage – Non-volatile memory for saving configurations Power Input 5V via USB Type-C port Automatically adapts to […]

ESP32-P4 revision 3.0 gains new power rail, requires new PCB design and firmware

Espressif’s ESP32-P4 revision 3.0 and greater converts pin 54 of the chip from NC (not connected) to a power rail (VDD_HP_1), requires a few extra passives, and an updated firmware. Espressif Systems first unveiled the 400 MHz ESP32-P4 dual-core RISC-V SoC in January 2023, and the official ESP32-P4-Function-EV development board was launched in August 2024, with commercial solutions slowly ramping up last year. You’d think the silicon and related hardware would now be frozen, but apparently not. The pin 54 was likely converted from NC (not connected) to VDD_HP_1 to improve the stability of the high-performance digital domain. The old revisions 1.0, 1.1, and 1.3 are not recommended for new designs, and the company advises people to use revision 3.0 or 3.1. They also provided updated reference schematics with the following key changes: The main differences between chip revisions v1.0/v1.3 (not recommended for new designs) and v3.0 and later versions […]

KiCad 10 release – Dark mode, graphical DRC rule editor, new file importers, and more

KiCad 10 open-source EDA software has just been released with support for dark mode, importers for Allegro, PADS, and gEDA/Lepton PCB, and various changes to the Schematic Editor (e.g., hop-over display) and the PCB Editor, notably adding a graphical DRC rule editor. KiCad 10 was built by hundreds of developers, translators, library contributors, and documentation submitters, who submitted 7,609 unique commits after KiCad 9 was released in February 2025. The new version also gains 952 new symbols, 1216 new footprints, and 386 new 3D models. Some UI and usability improvements include dark mode support (Windows only), customizable toolbars, undo/redo support in dialogs, lasso/freeform selection instead of only rectangular selection, and new importers for Allegro, PADS, and gEDA/Lepton PCB. Schematic editing gains support for variants (e.g., single project with different BoM), hop-over display, jumper support, grouping support, and pin table CSV export/import. PCB Design adds time-domain tuning beyond just length constraints […]

DSG-22.6 GHz is a $1,590 open-source RF signal generator based on Atek Midas’s custom ICs (Crowdfunding)

DSG 22.6 GHz RF signal generator block diagram

Atek Midas, a Turkish company, has launched DSG-22.6 GHz, a high-performance, open-source RF signal generator designed to provide professional-grade frequency synthesis at a fraction of the cost of traditional benchtop equipment from manufacturers like Anritsu or Keysight. It has an operating frequency range of 0.15 GHz to 22.6 GHz and is designed for makers and production test environments for RF testing, calibration, wireless experimentation, and microwave research. The device offers 1 Hz tuning resolution, adjustable output power −15 dBm to +20 dBm, and supports linear and logarithmic frequency sweeps with configurable start/stop frequencies, step size, and dwell time. It achieves ≥40 dBc spurious and harmonic suppression on the filtered output path and features a tuning speed of <100 µs. The generator includes a capacitive touchscreen display and can also be controlled over a USB Type-C port and/or Wi-Fi. DSG-22.6 GHz specifications: Frequency range – 150 MHz to 22.6 GHz Tuning […]

Electronic components price and lead time increases announced across the board, and not only because of RAM

Most people already know about rapidly rising RAM prices, but I’m receiving more and more emails about price increases for a range of devices, in a way that’s reminiscent of the impact the Coronavirus/COVID-19 had in 2020 to 2022. We’ve already covered the Raspberry Pi Compute Modules price increase in October 2025, followed by the Raspberry Pi 4/5 price adjustment last December. Unsurprisingly, it’s going to spread to other companies as well. A few days ago, I received an email from SolidRun entitled “Customer Notification: Industry‑Wide Component Shortages and Price Increases”: The global semiconductor, and electronic components industry is currently experiencing significant price increases and widespread shortages. What started as memories shortage covering mostly DDR4 and NAND integrated circuits and modules – expanded across multiple categories (including SoCs). As a result, many critical components now face extended lead times, with certain items that were previously available within a few weeks […]
