ASUS Tinker Edge R SBC with 3GB RAM, Rockchip RK3399Pro sells for $179

ASUS Tinker Edge R Pico-ITX single board computer with Rockchip RK3399Pro AI processor was first unveiled in 2019 with 6GB RAM, but a cheaper 3GB RAM version with 2GB RAM for the CPU, and 1GB RAM with the integrated NPU just showed up in my news feeds. Whether it comes with 3GB or 6GB RAM, the Tinker Edge R board should mostly be interesting for AI accelerated workload thanks to the 3 TOPS built-in NPU, as well as the two MIPI CSI camera interfaces. ASUS Tinker Edge R (3GB) SBC specifications: SoC – Rochchip RK3399Pro hexa-core big.LITTLE processor with 2x Cortex A72 cores up to 1.8 GHz, 4x Cortex A53 cores @ 1.4 GHz, an Arm Mali-T860 MP4 GPU up to 800 MHz with OpenGL ES 1.1 to 3.2, OpenVG1.1, OpenCL 1.2 and DX 11 support, and NPU delivering up to 3.0 TOPS System Memory – 2 GB dual-channel LPDDR4 […]

Quadric devkit features q16 hybrid AI, DSP, computer vision accelerator

The Quadric devkit is an M.2 Key M module equipped with the company’s q16 edge processor offering a hybrid data-flow + Von Neumann machine for not only neural networks, but also computer vision, digital signal processing, BLAS (Basic Linear Algebra Subprograms), and other workloads. This architecture allows the Quadric q16 to be more flexible than traditional AI accelerators and can deliver more effective solutions for heterogonous systems that may have multiple accelerators or require a powerful processor. The M.2 form factor enables easy integration into boards with an M.2 Key M socket such as the Gumstix Raspberry Pi 4 development board shown below with the Quadric devkit. Quadric devkit specifications: Accelerator – Quadric q16x4 Processor with 256 Vortex Cores, 8 MB on-chip memory, 4 kB per core memory, multi-precision multiply accumulate; 16 x 16mm package Memory – 4GB LPDDR4, 32-bit, dual-rank up to 3677 MHz Host Interface – 2-lane PCIe […]

Arduino Nicla Vision – A tiny STM32H7 board with 2MP camera, WiFi & Bluetooth LE, sensors

Arduino Nicla Vision is an ultra-compact (~2.3×2.3 cm) board powered by an STMicro STM32H7 dual-core Cortex-M7/M4 microcontroller, and equipped with a 2MP camera, a WiFi & Bluetooth LE module, and a few sensors. Those features make the board suitable for machine vision and edge computing applications such as asset tracking, image detection, object recognition, and predictive maintenance. For instance, image detection, facial recognition, automated optical inspection, vehicle plate reading, or gesture recognition can be added to projects, either using Nicla Vision as a standalone board or in combination with Portenta or MKR boards. Arduino Nicla Vision specifications: Microcontrollers – STMicro STM32H757AII6 dual-core MCU with Arm Cortex M7 @ 480MHz, Cortex-M4 @ 240MHz, 2 MB flash, 1MB RAM Storage – 16MB QSPI flash Connectivity – 2.4GHz WiFi 802.11b/g/n up to 65 Mbps and Bluetooth 5.1 BR/EDR/LE via Murata 1DX module Camera – 2MP GC2145 color camera. USB – Micro USB port […]

Blues Wireless launches Wi-Fi Notecard for mixed cellular & WiFi IoT deployments

Blues Wireless has just launched the Wi-Fi Notecard M.2 module that can be used as a replacement to the company’s Notecard LTE Cat-M / NB-IoT M.2 modem that sells with 10 years of connectivity up to 500MB for $49 and up. The Wi-Fi Notecard came to be as some customers wanted to have mixed deployments where cellular makes sense in some locations, while Wi-Fi is better suited to other sites. Others preferred to use WiFi during development or prototyping to save on Notecard cellular data usage. Wi-Fi Notecard specifications: MCU – Arm Cortex-M4 MCU with 2MB flash Wireless Silicon Labs WFM200S Wi-Fi transceiver module with a 2.4 GHz 802.11b/g/n radio supporting up to 72 Mbps link u.FL antenna connector Host interface – M.2 edge connector with I2C, UART, USB Sensor – 3-axis accelerometer and temperature sensor Security – STSAFE Secure Element with hardware crypto, true hardware random number generator, and […]

Maker Nano RP2040 offers Arduino Nano, Grove and Qwiic modules compatibility

Cytron Maker Nano RP2040 is board similar to Raspberry Pi Pico but with Arduino Nano form factor, a proper reset button, two RGB LEDs, single color LEDs for some GPIOs, a buzzer, as well as two Qwicc/STEMMA QT connectors that can also be used to connect Seeed Studio Grove modules using provided conversion cables. While the board mostly aims to be an Arduino Nano/Maker Nano upgrade, there are some notable differences with the I/O voltage being limited to 3.3V without 5V tolerance, and there are only four ADC inputs (A0 – A3) instead of eight on the Arduino Nano. Maker Nano RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 125 MHz with 264KB internal RAM Storage – 2MB flash Audio – Piezo buzzer with mute switch Expansion 2x 15-pin headers with 22x GPIOs, 14x of which with LEDs,2x I2C, 2x UART, 2x SPI, 14x PWM, 4x […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others.   Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]

Linux 5.16 Release – Main Changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 5.16: Not a lot here since -rc8, which is not unexpected. We had that extra week due to the holidays, and it’s not like we had lots of last-minute things that needed to be sorted out. So this mainly contains some driver fixes (mainly networking and rdma), a cgroup credential use fix, a few core networking fixes, a couple of last-minute reverts, and some other random noise. The appended shortlog is so small that you might as well scroll through it. This obviously means that the merge window for 5.17 opens tomorrow, and I’m happy to say I already have several pending early pull requests. I wish I had even more, because this merge window is going to be somewhat painful due to unfortunate travel for family reasons. So I’ll be doing most of it on the road on a laptop […]
