Made in Thailand CorgiDude RISC-V AI board aims to teach machine learning

There’s a relatively small but active maker community in Thailand, and we’ve covered or even reviewed some made in Thailand boards including ESP8266 and ESP32 boards, a 3G Raspberry Pi HAT, and KidBright education platform among others. MakerAsia has developed CorgiDude, a board based on the version of Sipeed M1 RISC-V AI module with built-in WiFi, and part as a kit with a camera and a display used to teach machine learning and artificial intelligence with MicroPython or C/C++ programming. CorgiDude board specifications: AI Wireless Module – Sipeed M1W Module with Kendryte K210 dual-core 64-bit RISC-V RV64IMAFDC CPU @ 400Mhz with FPU, various AI accelerators (KPU, FFT accelerator…), 8MiB on-chip SRAM Espressif ESP8285 single-core 2.4 GHz WiFi 4 SoC plus IPEX antenna connector Storage – MicroSD card slot Camera I/F for 2MP OV2640 sensor up to 1280 × 1024 (SXGA) @ 30 fosm SVGA @ 30 fps, or CIF @ […]

CutiePi tablet gets a Raspberry Pi CM4 upgrade

CutiePi tablet was launched on Kickstarter last year with a Raspberry Pi Compute Module 3+ Lite, an open-source hardware carrier board, and an 8-inch multi-touch display with 1280×800 resolution. Shipping to backers is about to start, but the company has already started working on a new version of the CutiePi Tablet with the Raspberry Pi CM4 module released last October. This will enable greater performance and more memory with the tablet shipping with a 2GB RAM CM4 module by default. CutiePi CM4 tablet preliminary specifications: SoM – Raspberry Pi Compute Module 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 2GB RAM Storage – MicroSD card slot Display – 8-inch 5-point multi-touch IPS LCD with 1280×800 resolution Video Output – Micro HDMI Audio – 2W 8Ohm speaker, audio amplifier, built-in microphone Camera – 5MP front-facing camera (OV5647) Connectivity – Dual-band 802.11 b/g/n/ac WiFi 5 and Bluetooth 5.0 USB […]

Annke CZ400 AI security camera reviewed with basic and smart events

At the beginning of this month, I started the review of Annke CZ400 AI security camera by listing specifications, unboxing the device, and doing a partial teardown, notably to install a MicroSD card. In theory, the camera comes with more advanced AI features than Reolink RLC-810A 4K CCTV camera that only supports people and vehicle detection, as the Annke security camera can handle face detection, line crossing, unattended baggage detection, and other smart event detections. So let’s see how it performs Annke CZ400 installation The first challenge was the installation, as I told the company I would not be willing to install the camera on the ceiling since I’m renting, and preferred wall-mounting. after checking the user manual that included a wall mount, I decided to go ahead, and get the review unit. But sadly, the wall mount is not included in the package, and Annke even told me they […]

Windows Performance on an Intel NUC 11 Enthusiast Phantom Canyon NUC11PHKi7C

The Enthusiast Phantom Canyon is Intel’s flagship product from its latest NUC 11 range of mini PCs. Specifically targeting gamers it includes an NVIDIA RTX 2060 GPU. In this article, I take a brief look at the performance under Windows and compare it against Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon. Hardware Overview The NUC11PHKi7C physically consists of a 221 x 142 x 42 mm (8.70 x 5.59 x 1.65 inches) rectangular plastic case which is remarkable because of its size and is similar to just a graphics card like NVIDIA’s GeForce RTX 2060 Founders Edition (229 x 113 x 35 mm). It is an actively cooled mini PC and uses Intel’s 10 nm Core i7-1165G7 Tiger Lake processor which is a quad-core 8-thread 2.80 GHz processor boosting to 4.70 GHz with Intel’s Iris Xe Graphics. But it also includes NVIDIA’s N18E-G1-B notebook graphics […]

Zymbit HSM4 & HSM6 security modules work with embedded Linux hardware, Raspberry Pi, Jetson Nano

Zymbit Zymkey security modules, now called Zymkey4i, were first introduced several years ago. Based on the Microchip ATECC508A CryptoAuthentication chip, the modules were available as a USB stick, an I2C module for Raspberry Pi boards, or an SMT component, and designed to enable multifactor device ID & authentication, data encryption & signing, key storage & generation, and physical tamper detection. The company has now informed CNX Software they had launched HSM4 cryptographic protection module and HSM6 hardware wallet with a different form factor for easy integration into embedded applications, and devkits compatible with Jetson Nano and Raspberry Pi SBCs. Zymbit HSM4 cryptographic protection module & devkit HSM4 crypto module key features and specifications: HSM4 is built upon Zymkey4i module, and integrates an Arm Cortex-M0 microcontroller, as well as a secure element likely to be Microchip ATECC508A, or the more recent ATECC608B CryptoAuthentication chip if the company upgrade System Identity & […]
