SmartBug smart switch integrates neatly into in-wall sockets (Crowdfunding)

SmartBug is a smart switch based on ESP32 wireless SoC, equipped with several sensors to measure temperature, humidity, power usage, and listen to sounds. It is designed to fit neatly into most in-wall sockets found around the world. Each SmartBug relies on mesh networking to communicate with each other and extend the range, WiFi for Internet connection, and Bluetooth low energy (BLE) to control additional devices without the need for any additional hub. SmartBug’s key features: MCU – 32-bit dual-core microcontroller with WiFi, wireless mesh, Bluetooth LE Connectivity 2.4GHz WiFI 4 Wireless mesh to let SmartBug act as a signal repeater Bluetooth 4.0 and BLE to control home appliances Audio Digital microphone for voices commands, baby crying (only enable if the plugin is downloaded in the app). Buzzer On-Off Relay up to 2200W, both AC and DC. Sensors – Temperature & humidity sensor, built-in power meter (current, voltage, and power) […]

Jupiter Nano – Tiny Cortex-A5 board runs Linux or NuttX RTOS (Crowdfunding)

Jupiter Nano looks like one of those small MCU boards, but instead of a microcontroller, it packs a 500 MHz Microchip SAMA5 Cortex-A5 processor with 128MB RAM capable of running Linux or NuttX operating systems. The board reminds me of the Adafruit Feather compatible Giant Board made by Groboards, with the same system-in-package, but Juniper Nano offers more I/Os via 48 through holes, and its size is said to be similar to Teensy 4.1 board (but not quite). Jupiter Nano specifications: SiP – Microchip SAMA5D27C-LD1G with Cortex-A5 processor running at 498 MHz, 128MB LPDDR2 DRAM Storage – MicroSD card socket (bootable) USB – 1x Micro USB 2.0 host/device port, 1x USB 2.0 host on header Expansion – 2x 24-pin headers with GPIOs, USB, SPI, I2C, up to 4x Flexcom interfaces configurable as SPI, UART or I2C Programming – JTAG port, Micro USB 2.0 FS debug console via MCP2200 USB-UART converter […]

BeagleV Starlight SBC won’t be mass manufactured, redesigned BeagleV RISC-V SBC expected in Q1 2022

There was lots of excitement when BeagleV Starlight single board computer was announced in January of this year. With a price tag of $119 and up, it promises to be an affordable RISC-V SBC with StarFive JH7100 dual-core SiFive U74 Vision SoC with AI accelerator, H.265/H.264 hardware video decoding, up to 8GB RAM, HDMI output, Gigabit Ethernet, and so on. Several beta testers even received BeagleV Startlight prototypes, providing instructions for buildroot, boot Linux, or even a video review with Fedora. The first version lacked a GPU, and the initial schedule planned for a new revision with an Imagination GPU to be manufactured in September. But there have been some changes, as BeagleV Starlight SBC will not go into mass production, but not all is lost, as the Foundation and Seeed Studio are working on a new BeagleV community board slated to be released in Q1 2022. Drew Fustini made […]

Amazon Alexa certified ESP AFE leverages ESP32-S3 AI & DSP instructions

While most Amazon Alexa certified products are hardware designs, Amazon website also includes a Software Audio Front End (AFE) Dev Kits section that lists software algorithms that optimize audio detection in noisy environments, and the latest addition is Espressif’s Audio Front-End algorithms, or ESP AFE for shorts, that have recently been qualified for Amazon Alexa devices. It’s not the first Alexa certified solution from Espressif Systems, as both companies have worked together in the past with audio products like the ESP32-PICO-V3-ZERO Alexa Connect Kit Module or ESP32-Vaquita-DSPG board The algorithms were created by Espressif’s AI Lab team who used the AI and DSP instructions inside ESP32-S3 processor to optimize the code. The algorithms only utilized 12 to 20% of the CPU, as well as 220 KB of internal and 240 KB of external memory, leaving extra resources for other applications running in the wireless SoC. The ESP AFE is said […]

XGO Mini Pro robot dog features Kendryte K510 AI processor (Crowdfunding)

Kendryte K510 RISC-V AI processor is the successor of Kendryte K210 with much more AI processing power (2.5/3 TOPS) that makes it suitable for robotics projects demanding much lower latency and quasi-real-time inference. One of the first products to make use of Kendryte K510 capabilities is Luwu Intelligence Technology’s XGO Mini Pro, a four-legged robot that looks like a dog with a tiny head providing the “smarts” for the system including face detection, image recognition, object tracking, voice recognition, and so on. The description of the robot on Canaan’s website is rather short with an explanation that when equipped with is equipped with a 9-axis IMU and joint positioning sensors, providing behavioral and joint feedback. The head is exchangeable and when using the earlier Kendryte K210, the robot is capable of omnidirectional movements, six-dimensional navigation control, and stabilization support, as well as multiple movement modes. Kendryte K510 enables more features […]

25-45W Intel Tiger Lake-H Xeon, Core, and Celeron embedded processors coming soon

While doing some research, I noticed an Intel Core i7-11850HE “Tiger Lake-H” processor on the OpenVino Toolkit website. Parts that end with “E” are usually processors designed for the embedded market. I had never heard about the Tiger Lake-H embedded family, so I looked for “i7-11850HE” processor, and it’s not in Intel Ark, or much anywhere else except on a page in Google Cache, about a COM-HPC module “with the 11th Gen Intel® Xeon® W-11000E Series, Core™ vPro® and Celeron® processors (formerly Tiger Lake-H) for FuSa application”. There we have a list of Xeon, Core, and Celeron 11th generation processors that I don’t think have ever been announced: Intel Celeron 6600HE dual-core processor @ 2.6GHz with 8MB L3 Cache, 35W TDP Intel Core i3-11100HE processor with 4 cores / 8 threads @ 2.4GHz (up to 4.4GHz in Turbo Boost) with 8MB L3 Cache, 45/35W cTDP Intel Core vPRO i5-11500HE processor […]

NuCurrent showcases NFC charging at 3W, data rates up to 848 kb/s

The NFC Forum approved the Global Wireless Charging (WLC) specification last year with the new standard making it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt. The NFC WLC currently specifies power levels ranging from 100mW – 1W transmitted and data rates up to 106 kb/s, but NuCurrent claims to have gone beyond WLC specs, delivering over 3x more wireless power and over 8x faster data speeds. This was achieved with the company’s NuEva Development Platform for Near-Field Communication (NFC) Wireless Charging technology that provided up to 3W of power received (as opposed to just transmitted in the WLC specification) and data rates of up to 848 kb/s. NuCurrent expects the higher NFC charging power and data rates to enable new applications for small, space-constrained devices including wrist-wearables, smartwatches, styluses, […]
