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. Xero MCU specifications: Microcontroller – STMicro STM32F411CEU6 Arm Cortex-M4F MCU @ 100MHz with 512KB Flash, 128KB SRAM USB – 1x USB Type-C port for power and programming Expansion – 2x 20-pin through and castelled holes with up to 17x GPIO, I2C, 2x SPI, 2x UART, 4x ADC, 5V, 3.3V, and GND Debugging – 4-pin debug connector […]

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 […]

MicroPython-programmable OpenMV N6 and AE3 AI camera boards run on battery for years (Crowdfunding)

OpenMV has launched two new edge AI camera boards programmable with MicroPython: the OpenMV AE3 powered by an Alif Ensemble E3 dual Cortex-M55, dual Ethos-U55 micro NPU SoC, and the larger OpenMV N6 board based on an STMicro STM32N6 Cortex-M55 microcontroller with a 1 GHz Neural-ART AI/ML accelerator. Both can run machine vision workloads for several years on a single battery charge. The OpenMV team has made several MCU-based camera boards and corresponding OpenMV firmware for computer vision, and we first noticed the company when they launched the STM32F427-based OpenMV Cam back in 2015. A lot of progress has been made over the years in terms of hardware, firmware, and software, but the inclusion of AI accelerators inside microcontrollers provides a leap in performance, and the new OpenMV N6 and AE3 are more than 100x faster than previous OpenMV Cams for AI workloads. For example, users can now run object […]
