ARM Introduces Secure Cortex-M23 and Cortex-M33 ARMv8-M MCU Cores, and Bluetooth 5 Cordio Radio IP for IoT Applications

ARM TechCon 2016 is now taking place in Santa Clara, California, USA, as ARM has made three announcements for the Internet of Things, the focus of SoftBank going forward, with two ARM Cortex-M ARMv8-M cores integrating ARM TrustZone technology, namely Cortex-M23 low power small footprint core, and Cortex-M33 core with processing power similar to Cortex-M3/M4 cores, as well as Cordio Radio IP for Bluetooth 5 and 802.15.4 connectivity. ARM Cortex-M23 ARM Cortex-M23, based on the ARMv8-M baseline architecture, is the smallest and most energy efficient ARM processor with TrustZone security technology,and targets embedded applications requiring both a small footprint, low power, and security. Its power consumption is low enough to be used in batteryless, energy harvesting IoT nodes, and is roughly a third of Cortex-M33 processor size, and offers more than twice its energy efficiency. Cortex-M23 is a two-stage pipelined processor, software compatible with other processors in the Cortex-M family. […]

Webduino Smart ESP8266 Board is Designed to be Programmed via Websocket and Blockly Editor

Webduino Smart board reminds me of Witty ESP8266 board with its RGB LED and photocell sensor, but the design is a little different, and does not come with an extra USB to TTL board, as it’s designed to be programmed over the air using Blockly Editor. Webduino Smart specifications: WiFi Module – AI Thinker ESP-12F module with Espressif ESP8266 WiSoC Connectivity – WiFi 802.11 b/g/n 2x 8-pin headers with GPIOs,  ADC (Connected to Photocell), UART, VCC, 3.3V, GND, and Reset.

Vocore2 Lite is a $4 Linux MIPS WiFi Module based on Mediatek MT7688AN SoC (Crowdfunding)

I’ve already written about Vocore v2 Crowdfunding campaign, where the second generation Vocore WiFi module supports audio, PoE, and ultimate dock, and price starting at $12. But there has been some development since the launch of the campaign, as the developer received request for a cheaper board, and after looking into it, has now added Vocore2 Lite WiFi module reward for only $4, or $7 once shipping included. He obviously had to make some trade-offs to bring the cost down, but the Lite board impressively still keep many of the same features. VoCore (2014) VoCore2 Lite (2016) VoCore2 (2016) Price 19.99 USD 3.99 USD 11.99 USD CPU RT5350, 360MHz MT7688AN MIPS24KEc @ 580MHz MT7628AN, 580MHz Memory 32MB SDRAM 64MB DDR2 128MB DDR2 Storage 16MB NOR 8MB NOR 16MB NOR Antenna Slot x1 x1 x2 On-Board ANTENNA √ × √ Wireless Speed ~75Mbps ~150Mbps ~300Mbps Ethernet Port x5 x1 / x5 […]

CHIP Pro is a $16 WiFi and Bluetooth 4.2 System-on-Module Powered by a $6 GR8 ARM Cortex A8 SIP

Next Thing CHIP board and corresponding PocketCHIP portable Linux computer have been relatively popular due to their inexpensive price for the feature set, as for $9, you’d get an Allwinner R8 ARM Cortex A8 processor, 512MB flash, 4GB NAND flash, WiFi & Bluetooth connectivity, and plenty of I/Os, which made it very attractive for IoT applications compared to other cheap boards such as Raspberry Pi Zero and Orange Pi One. The first board was mostly designed for hobbyists, but  company has now designed a new lower profile system-on-module called CHIP Pro based on Next Thing GR8 SIP combining Allwinner R8 SoC with 256MB DDR3 RAM that can be used for easy integration into your own hardware project. While the original CHIP board exposed full USB ports and interface for video signal, the new CHIP Pro is specifically designed for IoT with the following specs: SIP – Allwinner R8 ARM Cortex […]

Exilong RF & WiFi Irrigation System Automatically Takes Care of Your Garden Watering (Crowdfunding)

I find it fun to spend time watering the flowers and grass in my garden, but if you’d rather do it automatically then Tevatronic Exilong might be for you as the irrigation system controls up to 4 valves, triggers watering based on RF water sensing sensors via a gateway connected to the cloud through your wireless router. The kit gateway takes care of RF communication with sensors, WiFi connectivity to the cloud server, and turn on and off up to four 24V DC water valve part of your existing installation. It can be configured by iOS or Android mobile app, or your web browser. The other part of the kit are the water pressure sensors that you need to insert into the soil of your garden in order to monitor trees, bushes, and/or flowers. The sensors are using RF (433/915 MHz) communication, send data back to the gateway every minute, […]
