Toybrick TB-RK1808 AI Compute Stick is now Available for $86

Last May, we wrote about RK1808 AI Compute Stick, a USB stick with Rockchip RK1808 dual-core Cortex-A35 processor also featuring a 3.0 TOPS neural processing unit to accelerate AI workloads at low power. As I understood it, it was available for purchase, but you had to contact a Rockchip FAE by email in order to get one. Now, you can easily buy one online by getting the Toybrick TB-RK1808 AI Compute Stick on Seeed Studio for $86. Just ignore the “Core i3” in the title, we’ll see why it’s there further below. TB-RK1808 AI Compute Stick specifications: SoC – Rockchip RK1808 dual-core Cortex-A35 processor with NPU AI inference performance – 3 TOPS for INT8, 300 GOPS for INT16, 100 GOPS for FP16 System Memory – 1GB LPDDR Storage – 8GB eMMC flash Host Interface – USB 3.0 type-A port Power Supply – Via USB port Dimensions – 82 x 31 […]

Sonoff S55 Waterproof WiFi Smart Sockets are Offered in Six Regional Variants

When WiFi smart sockets (aka smart plugs) started to appear a few years ago, they were often only available with either US or China plugs, and users from Europe, UK or other locales may have had to use an adapter instead. Since then, products that ship with multiple versions such as Sonoff S26 or Orvibo Wiwo S20 have launched in order to cater to more people around the world. ITEAD has now launched another WiFi smart socket, namely Sonoff S55, that’s designed to work outdoors thanks to IP55 ingress protection rating, and is offered in six different variants for Australia, Germany, France, the United States, South Africa, and the United Kingdom. Sonoff S55 specifications: Input/Output S55TPI(AU) – AC 100-240V 50/60Hz 10A Max S55TPF(DE) – AC 100-240V 50/60Hz 16A Max S55TPE(FR) – AC 100-240V 50/60Hz 16A Max S55TPB(US) – AC 125V 50/60Hz 10A Max S55TPD(ZA)- AC 100-240V 50/60Hz 10A Max S55TPG(UK) […]

Socionext 24 GHz Radar Sensor for IoT Measures Distance and Angle (Video)

Last year, we wrote about Socionext MN87900 24 GHz radio wave radar module for IoT with Rx & Tx antennas and a crytal unit that measured just 12×7 mm. The module is made for IoT equipments, security systems, smart home appliances, autonomous vehicles and drones, medical devices, and more. Basically any application that requires distance measurement up to 8 meters (expandable to 30 meters with a radome horn), rough location, or motion detection may leverage the technology. The company has now uploaded a video showing a demo of their 24 GHz radar sensor. Socionext did not explain which exact solution they used, and it’s probably not the full module above, but either one of their sensors based on the link provided in the video description: SC1232AR3 – All-in-one RADAR sensor for Entry Motion & Distance Detection SC1233AR3 – All-in-one RADAR sensor for Entry Motion & 2D Detection I suspect SC1232AR3 […]

Allwinner R328 Smart Speaker & System-on-Module Spotted in China

Earlier this year, Allwinner introduced some AIoT (AI + IoT) processors including Allwinner R328 dual-core Cortex-A7 processor for “low-cost voice interaction solutions” aka low-cost smart speakers. I did not pay too much attention at the processor at the time, but since then, the company has released a product brief with some more details about the processor. We can see it integrates 64MB to 128MB DDR3 memory which should be enough to run Linux without external memory, and truly provide a low-cost solution for smart speakers, and I was told the chip may cost around $3. I was also asked whether Allwinner R328 smart speakers were already shipping. A Google search in English did not help, so I had to switch to Chinese, and after visiting several sites, I could see some Allwinner A328 platforms including a smart speaker and a system-on-module were showcased at some event in China. We’ve got […]

Onenuts Nut 9 TV Box Runs Android TV, Doubles as a Smart Speaker

We’ve previously covered HF10 2-in-1 Android speaker and TV box that looks more like a speaker than a TV box, and since we’ve posted about it several years got improved to work as a smart speaker supporting Amazon Alexa. If you’re a distributor looking for something with the same functionalities, but in a more compact TV box form factor, Shenzhen Tomato got you covered with their Onenuts Nut 9 TV box that works as a traditional TV box running Android TV 7.1, as well as a smart speaker with support Google Assistant even when the TV is off thanks to a built-in microphone and a speaker placed on the bottom of the enclosure. Onenuts Nut 9 specifications: SoC – Amlogic S905X Arm Cortex-A53 processor up to 1.5GHz with penta-core Mali-450MP GPU up to 750Mhz+ System Memory – 2GB DDR3 Storage – 16GB eMMC flash, micro SD card slot Video Output – […]

RAKWireless Introduces RAK7200 LoRa Tracker | Features & Specifications

RAK7200 is a LoRa Tracker node built around the AcSIP S76G chip. It integrates the ultra-low-power STM32L073 micro-controller, the SX1276 LoRa long range modem, and the CXD5603GF GPS receiver. The RAK7200, being a fully functioning LoRaWAN device, is particularly suited for IoT applications. Such as asset tracking, smart vehicle management, location-based service, etc. According to the device manufacturers, RAKWireless, a leading Chinese IoT solutions company, based in Shenzhen, RAK7200 requires minimal setup. Just pop in the included battery, close the housing and you can start sensing your GPS data over LoRaWAN. Furthermore, there are sensors built-into the board: a 9-axis accelerometer and pressure sensor. The new GPS Tracker node is an upgrade over the company’s earlier offering in the GPS tracker space, the RAK7205. Now, the earlier version, the RAK7205, was mostly aimed at developers, with its larger more robust casing and solar panel. But the RA7200 is more of […]

M5Stack M5StickV is a Tiny AI Camera for Maker Projects

I’ve just started to play with Maixduino board based on ESP32 WiSoC and Sipeed M1 module that enables AI tasks such as object detection thanks to built-in AI accelerators found in Kendryte K210 RISC-V processor and noticed references to M5Stack M5StickV in firmware file names. Somehow I never wrote about M5Stack, but the company provides modular ESP32 IoT development boards that can be stacked with various modules to easily and quickly build prototypes. M5StickV is one of those modules and is similar to Maixduino kit with camera and display, minus WiFi + Bluetooth connectivity, except that everything nicely packed into a cute module. M5StickV hardware specifications: SoC – Kendryte K210 dual-core 64-bit RISC-V processor @ 400MHz with dual independent double-precision FPU, 8MB on-chip SRAM, Neural Network Processor (KPU) @ 0.8Tops, Field-Programmable IO Array (FPIOA), and more Storage – 16MB flash, microSD card slot Display -1.14″ SPI display with 240×135 resolution […]

Wear Estimation for Devices with eMMC Flash Memory

flash wear leveling & garbage collection

CNXSoft: This is a guest post by Marcel Ziswiler, Platform Manager – Embedded Linux, Toradex and Leonardo Graboski Veiga, Technical Marketing Engineer, Toradex related to Marcel’s upcoming talk “Wear Estimation for Devices with eMMC Flash Memory” at the Embedded Linux Conference 2019 later this month. Flash memory has been an important topic in embedded systems for decades. It allows for drastic improvements to the size and robustness of electronic devices compared to other storage technologies. Other benefits of flash storage include a lack of moving parts and reduced power consumption. However, the challenges that come with flash memory are not as widely publicized in consumer electronics. Among them are limited durability and greater software complexity. As shown in Figure 1, flash memory is everywhere in our daily lives, ranging from devices used specifically to store data, such as thumb drives, SD cards and SSDs, to other consumer electronics that use […]
