Renesas RA8T1 Cortex-M85 MCU targets motor control applications

It took a while before Renesas released its first Arm Cortex-M85 microcontroller (RA8M1) in October 2023, but the company has now launched the RA8T1 Cortex-M85 MCU for motor control just a few weeks after announcing the RA8D1 for HMI applications. The RA8T1 group is the third Cortex-M85 microcontroller family from Renesas with a feature set optimized for motor control and leveraging machine learning through Arm Helium technology and a DSP for predictive maintenance requirements for motors. Renesas RA8T1 key features and specifications: MCU core – Arm Cortex-M85 clocked at 480 MHz with Helium MVE (M-Profile Vector Extension) with 32KB I/D caches, 12KB data flash Memory & Storage 1MB SRAM including 128KB TCM 1MB to 2MB Flash memory 2x SD/MMC host interfaces (SDHI) Communication interfaces Ethernet MAC with DMA USB – 1x USB 2.0 Full Speed interface 2x CAN-FD Up to 6x SCI (UART, Simple SPI, Simple I2C) 2x SPI up […]

Femto Mega 3D depth camera review – OrbbecViewer and Orbbec SDK in Ubuntu 22.04, body tracking in Windows 11

We had a quick look at the Orbbec Femto Mega 3D depth and 4K RGB camera at the end of last year with a look at the hardware and a quick try with the OrbbecViewer program in Ubuntu 22.04. I’ve now had the time to test the OrbbecViewer in more detail, check out the Orbbec SDK in Linux and various samples, and finally test the Femto Mega with a body tracking application using Unity in Windows 11. A closer look at OrbbecViewer program and settings As noted in the first part of the review, the OrbbecViewer program provides color, depth, and IR views for the camera. Let’s go into details for each. The Color mode would be the same as your standard USB color camera. The Femto Mega supports resolution from 1280×720 at 30 fps to 3840×2160 at 25 fps using MJPG, H.264, H.265, or RGB (converted from MJPG). We […]

NXP launches MCX A14x and MCX A15x Arm Cortex-M33 MCUs along with FRDM-MCXA153 development board

NXP has just announced the launch of the MCX A series Arm Cortex-M33 microcontrollers with the MCX A14x running up to 48 MHz and the MCX A15x running up to 96 MHz. The devices support up to 128KB flash and 32KB SRAM, offer I2C, I3C, and SPI sensor interfaces, and integrate support for BLDC/PMSM motor control. NXP first unveiled the NXP MCX general-purpose Arm MCU family with 30 times faster machine learning at Embedded World 2022, but at the time we had limited information although four series were planned with the MCX N Advanced series up to 250 MHz, the MCX A essential series up to 96 MHz, the MCX W Wireless series with Bluetooth LE, and the MCX L Low-power series. The MCX A series has just been launched, and the high-end MCX N also has its own product page with the N94x and N54x variants. We’ll focus on […]

EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]

Banana Pi BPI-M7 – A thin Rockchip RK3588 SBC with dual 2.5GbE, M.2 NVMe storage, HDMI 2.1, and more

Banana Pi BPI-M7 SBC is powered by a Rockchip RK3588 SoC and comes with a low profile design that reminds me of boards from Khadas such as the Khadas Edge2 or VIM4 SBCs but with a few extra ports thanks to the larger form factor. The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion. Banana Pi BPI-M7 specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76  cores @ up to 2.4 GHz, 4x Cortex‑A55 core @ 1.8 GHz GPU – Arm Mali-G610 MP4 “Odin” GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, […]

Review of SONOFF SNZB-03P new Zigbee motion sensor with eWelink and Home Assistant

SONOFF continues to release new Zigbee products series including the wireless switches/buttons (SNZB-01P) and temperature and humidity sensors (SNZB-02P) that we reviewed last year. Today, we will review another new sensor, that is the Zigbee 3.0 motion sensor (SNZB-03P) and we’ll need a Zigbee Hub/Bridge/Dongle to receive Zigbee signals to make it work. The technology of this sensor remains PIR, which uses infrared waves similar to before. This is different from the Human Presence sensors that are gaining popularity, which use mmWave (millimeter wave, frequency 3-30GHz). Both types have their pros and cons. SONOFF has also recently released a Human Presence sensor, namely the SNZB-06P which we will review soon. The SONOFF SNZB-03P is suitable for applications where motion needs to be detected (staying standstill won’t work) and places where it is not feasible or practical to run power cables. The latter is advantageous compared to Human Presence sensors because […]

SunFounder GalaxyRVR review – An Arduino programmable Mars Rover-like robot for education

SunFounder sent us a GalaxyRVR 6-wheel robot for review. It looks like NASA’s Mars Rover robots but targets the education market with an Arduino UNO R3 compatible board and an ESP32-CAM board for WiFi connectivity and video capture. The GalaxyRVR robot kit can transmit video signals over WiFi to explore planet Earth with your mobile device or tablet and the camera can be adjusted up and down thanks to a servo motor. The robot gets its power from a solar panel coupled with a battery and features sensors such as obstacle avoidance and ultrasonic modules. NASA’s Mars Rover exploration robots NASA is currently using the Perseverance rover, also known as Percy, as the latest planetary exploration robot to land on Mars. It is designed to explore the Jezero Crater as part of NASA’s Mars 2020 mission. In addition to its scientific instruments, Perseverance also carries Ingenuity, a small experimental Martian […]
