Brillo Android based OS for IoT Projects Supports ARM, Intel and MIPS Platforms

You’d think there are already enough lightweight operating systems that could provide a good enough platform for IoT and embedded projects, but Google decided to make their own Brillo operating system for IoT, based on Android, most probably to leverage the existing Android tools, and make it easier for app developers to move to the Internet of Things space. Brillo ‘s hardware requirements are pretty low as the operating system can run on devices with 32MB of RAM, and 128MB of storage. Google will provide a complete ecosystem with an embedded OS, core services, and a developer kit with tools to build, test, and debug. Just like in Android, three architectures will be be officially supports, starting with the following hardware platforms: ARM – TechNexion Pico-i.MX6UL system-on-module based on Freescale i.MX6 UltraLite and Broadcom BCM4339 802.11ac + Bluetooth 4.0 wireless module, combined with PICO-DWARF baseboard. MIPS – Upcoming MIPS Creator […]

ESP-14 WiFi Module Combines ESP8266 with STM8S MCU

ESP8266 WiFi modules can be purchased for less than $3, while some STM8S 8-bit MCUs board sell for just above $1. A.I. Thinker decided to combine both by adding an STMicro STM8S003 micro-controller to ESP-12E module and called that ESP-14. ESP-14 specifications: WiSoC – Expressif ESP8266-EX WiSoC MCU – STMicro STM8S003F3P6 8-bit MCU @ 16 MHz with 1KB RAM, 8KB flash, and 128 bytes EEPROM Connectivity – 802.11 b/g/n WiFi I/Os – STM8: 15 GPIOs also supporting I2C, SPI, UART, and up to 5 10-bit ADC ESP8266: E_GPIO0 to select operating mode (running or download) Power Supply – 3.3V Power Consumption – System Standby mode 70 mA; 0.5 μA shutdown @3.3V Dimensions – 24 x 16 mm STM8S controls ESP8266 by AT commands, and all but one of the I/Os are directly connected to STM8S. I can see at least two advantages: 5 ADC inputs are available, and for battery […]

ARM Introduces Mali-470 GPU for Wearables, IoT and Embedded Applications

Mali-400 was announced in 2008, and since then has been used in various SoCs for smartphone, but now it’s mostly replaced by Mali-450 GPU in low cost mobile and STB SoCs, although Mali-400 is still being implemented in new SoCs such as Rockchip RK3128 processor. ARM has been working on a lower power version of the GPU, and just unveiled Mali-470 GPU targeting wearables, as well as embedded and IoT applications. Mali-470 GPU is said to use the same memory and AMBA interfaces as Mali-400, while keeping some of the improvements brought to Mali-450 GPU, and further lowering power consumption to just half of that Mali-400 in terms of mW per frames per second. Just like its predecessors, Mali-470 supports OpenGL ES 2.0, and like Mali-400 it will scale from 1 to 4 fragment processor, always combined with one single vertex processor. Mali-470MP1 is likely to be used in wearables […]

Arduino 101 Board Features Intel Curie Module, Bluetooth LE, and Sensors

I’ve recently learned that the battle between the two Arduino teams, namely Arduino SRL (arduino.org) in Italy, and Arduino LLC (arduino.cc) in the US, had taken another turn with Arduino LLC now branding their boards as Arduino in the US, and Genuino in the rest of the world. This may certainly bring confusion to new comers, especially as they have to deal with different version of the Arduino IDE. With that backdrop, Arduino LLC has now introduced Arduino 101 (aka Genuino 101) board powered by Intel Curie module with Quark SE x86 SoC with Bluetooth LE and a 6-axis combo sensor. Arduino 101 specifications: SoC – Intel Curie compute module including an Intel Quark SE x86 32-bit microcontroller @ 32 MHz and an a DSP sensor hub @ 32Mhz with 384 KB flash, 80 KB SRAM (24KB available for sketches), , Bluetooth LE, and 6-axis combo sensor with accelerometer and […]

Marvell EZ-Connect MW302 IoT Starter Kit Supports AWS IoT Cloud Services

Amazon has just launched AWS (Amazon Web Services) IoT (Beta), a cloud platform that lets connected devices securely interact with cloud applications and other IoT devices. As pasrt of the announcement, they also released AWS IoT SDK that comes in three flavors: Embedded C SDK for C-based platforms such as Linux, RTOS, with variants for OpenSSL and mbed TLS. JavaScript SDK in Node.js Arduino Yún SDK. Ten started kits are currently officially supported by AWT IoT, many of them being existing platforms such as LinkIt One, BeagleBone Green, Intel Edison, or TI LaunchPad CC3200, with several of these kits including SeeedStudio’s Grove modules. One of the kits that’s completely new, at least to me, is Marvell EZ-Connect MW302 IoT Starter Kit which include a mini USB to USB cable, and Marvell 88MW302 development board with the following (preliminary) specifications: SoC – Marvell EZ-Connect MW302 ARM Cortex-M4 WiSoC with 512KB SRAM […]
