Secure IoT Connectivity with NodeMCU ESP8266 Board, ATECC508A Crypto Chip, Mongoose OS, and AWS IoT

There are many examples of Internet of Things projects, but more often than not the implementation is not secure, either because the device is exposed to the Internet with minimum or no security (worst case), or a gateway (hopefully) provides secure connection to the Internet, but the communication between sensor nodes and the gateway in the local network is not secure, due to memory limitation of the nodes, for example it might be challenging to implement security on ESP8266. Mongoose OS is an open source operating system for the Internet of Things developed by Cesanta working on ESP32, ESP8266, STM32, and TI CC3200, and the developers have demonstrated a secure solution with Mongoose OS running on ESP8266 connecting over a TLS connection to AWS IoT (Amazon Web Service IoT) and using TLS credentials stored in Microchip ATECC508A CryptoAuthentication Device. The addition of ATECC508 chip either using “XplainedPro extension board for […]

Arrow Chameleon96 Board To Feature Intel Altera Cyclone V SE FPGA + ARM SoC in 96Boards Form Factor

Embedded World 2017 will start in about one week, and take place in March 14 – 16 in Nuremberg, Germany, so we can expect interesting embedded news coming soon. Arrow has written a blog post with plans to announce three 96Boards at the event: Meerkat based on NXP i.MX 7Dual, Chameleon96 based on Intel/Altera Cyclone V FPGA + ARM SoC, and Systart Oxalis 96Boards EE board powered by NXP LS1020A single core ARM Cortex A53 SoC. I’ll start with Chameleon (Chameleon96) today, as it’s the first with FPGA fabric, and I could find some technical details and photos about the board. Chameleon96 board specifications: SoC – Intel PSG / Altera Cyclone V SE 5CSEBA6U19I7N with a dual core ARM Cortex A9 processor @ up to 800 MHz and FPGA fabric with 110K Logic Elements Chips, Ports and Features connected to FPGA: Integrated USB-Blaster II JTAG cable Configuration sources: SD Card, […]

$12 AI Light ESP8266 based WiFi RGB Light Bulb Supports MQTT via ESPurna Open Source Firmware

AI-Thinker is famous in the maker world for their ESP8266 modules, but they’ve also recently launched a WiFi RGB light bulb that sells for about $12.5 and up on eBay and Aliexpress. Some people noticed, and bought samples online, including Xose Pérez (aka Tinkerman), ESPurna open-source firmware developer, who could confirm ESP8266 was used in the light bulb, did some investigations, and eventually added the light bulb into ESPurna, which means it can be managed using MQTT or a web interface. AI Light looks very similar to Philips Hue, but comes with WiFi instead of Zigbee. AI Light “M1636” key features: RGBW LED E27 bulb with 16.7M colors Connectivity – 802.11 b/g/n WiFi Encryption – AES Voltage Range – 110-240V LED Power – 5 watts WiFi Power Consumption – ≤0.3W Temperature Range – -5~45degree Humidity – ≤80% Certifications – FCC, CE, ROHS If you’re going to use the stock firmware, […]
