ST’s Human Presence Detection (HPD) solution tracks head and posture with AI and VL53L8CP ToF sensor

VL53L8CP ToF sensor for AI presence detection

Back in 2022, we first saw STMicro launch the VL53L5CP ToF presence detection sensor for the PC market with features like user detection, gesture recognition, and intruder alert. Building upon that, the company has recently released its 5th‑generation Human Presence Detection (HPD) solution, built around the VL53L8CP 8×8 multizone Time‑of‑Flight sensor family with edge AI features offered as a turnkey solution for laptops, PCs, monitors, and accessories. We have seen and even tested earlier ToF sensors like the VL53L0X and VL53L1X, which used a single-photon avalanche diode (SPAD) for single-zone ranging. After that, we saw ST release the VL53L5, which was a major upgrade with up to 64-zone multi-zone support, enabling features like touch-to-focus and object tracking. Now, in the age of AI, ST has launched a 5th-gen turnkey HPD solution built around the VL53L8CP sensor. STMicro HPD solution specifications: Sensor – ST FlightSense VL53L8CP 5th generation multi-zone direct Time-of-Flight (dToF) […]

MicroSui lightweight, open-source C framework brings the Sui Network to microcontrollers

MicroSui (Sui Embedded Framework) is a lightweight, modular, open-source C framework that brings the Sui Network to microcontrollers from low-end 8-bit MCUs like AVR to more powerful 32-bit SoCs like the ESP32. Wait… What’s the Sui Network / Protocol exactly? It’s a blockchain platform designed for high-speed, scalable, and low-cost decentralized applications, which was introduced in May 2023 by Mysten Labs, a company founded by former Meta engineers. It competes with networks like Solana and Ethereum but with better performance. So far, the Sui Network works with web and mobile applications, but MicroSui aims to expand its usage to resource-constrained embedded devices. We’re told MicroSui provides support for all core operations such as key management, transaction construction, signing, and broadcast. It is a pure-C library with no OS dependency or dynamic memory usage, so it can be deployed on a wide range of microcontrollers. Higher-end microcontrollers with Internet access, such […]

Xero MCU is a compact USB-C board based on STM32F411 microcontroller (Crowdfunding)

Xero MCU is a small STMicro STM32F411 Arm Cortex-M4F microcontroller board with a USB-C port, twenty through and castellated holes for GPIOs, a Debug connector, Reset and Boot buttons, and a few LEDs. The 100 MHz MCU embeds 512KB flash and 128KB SRAM, and the board is said to be designed for hobbyists, students, and professionals. For reference, the Xero MCU board features the same STM32F411CEU6 microcontroller found in the Black Bill board. However, it’s quite shorter at about half the size, and features castellated edges, making it suitable for soldering on a baseboard.

STMicro STM32MP23 Cortex-A35/M33 MPU features a 600 GOPS NPU for industrial IoT and ML applications

STMicroelectronics STM32MP23 is a dual-core Cortex-A35 general-purpose microprocessor (MPU) with a Cortex-M33 real-time core, and 600 GOPS of performance operating at up to 125°C and designed for industrial and Internet-of-Things (IoT) edge computing, advanced HMI, and machine-learning (ML) applications. It follows the STM32MP25 series unveiled in 2023 and launched the following year as the first member of the STM32MP2 family. The STM32MP23 is a cost-down version of the STM32MP25 with similar specifications (and pin-to-pin compatible packages), but the new family has a weaker 0.6 TOPS NPU, and tops at two Ethernet ports for the high-end parts instead of three. Ditto for CAN Bus interfaces (2x vs 3x). Other changes include a 16-bit memory interface and the lack of PCIe and USB 3.0 interfaces. STM32MP23 specifications: CPU – Single or dual Arm Cortex-A35 cores running at up to 1.5 GHz or 1.2 GHz with 512KB L2 cache Real-time MCU – Arm […]
