$10 WiFiMCU Board is a NodeMCU Clone Based on EMW3165 Module

Yesterday I wrote a short tutorial for NodeMCU board, and one visitor mentioned WiFiMCU board that has a similar form factor as NodeMCU, and while it is more expensive at about $10 on Aliexpress or Ebay, it is also more powerful and provides more I/Os thanks to its EMW3165 module including an STM32 Cortex M4 micro-controller with 128KB RAM, 512KB flash, a Broadcom WiFi module, and 2MB SPI flash. WiFiMCU specifications: MCU – STMicro STM32F411CE Cortex-M4 microcontroller @ 100MHz with 128KB RAM, 512KB flash Storage – 2MB SPI flash WiFi –  Broadcom 802.11 b/g/n RF Chip: Modes – Station, Soft AP and Station+Soft AP Security – WEP, WPA/WPA2, PSK/Enterprise 16.5dBm@11b, 14.5dBm@11g, 13.5dBm@11n Receiver sensitivity – -87 dBm 2x 15-pin headers with 17x GPIO Pin 3x UARTs 5x ADC, 1x SPI, 1x I2C, 1x USB SWD debug interface 11x PWM Misc – Boot and Reset buttons Power Supply – 5V via […]

Altair FourGee LTE Chipsets Promise 10 Years of Connectivity with AA Batteries for IoT Applications

Connectivity achieved with GSM,. 3G or LTE (4G) cellular networks is great for long distances, but usually costs and power consumption are too high for IoT or M2M communications, which explains why there are competing long range low power WAN standards such as Sigfox, LoRA or Weightless. Altair Semiconductor introduced two new LTE SoCs, namely FourGee-1150/6410 and FourGee-1160/6410 a few months ago, supporting respectively LTE Cat-0 and Cat-1 connectivity, and promising up to 10 years of battery life on AA batteries for smart meters, wearables, security alarms, city lightings, etc… Altair FourGee-1150 and FourGee-1160 key features and specifications: Processor – Multiple MIPS M5150 “Warrior” MCU cores LTE Connectivity FourGee-1150 LTE Release 12 Category-0 (1Mbps / 1Mbps), software upgradeable for supporting Release 13 features Integrated VoLTE/IMS/OTA-DM functionality FourGee-1160 LTE Release 11 Category-1 (10Mbps / 5Mbps), software upgradeable for supporting Releases 12 and 13 features Integrated VoLTE/IMS/OTA-DM with HD voice functionality Software […]

Getting Started with NodeMCU Board Powered by ESP8266 WiSoC

Since ESP8266 is now so popular, I’ve recently bought a NodeMCU board to try it. I selected this board because the latest version of the board is breadboard-friendly, integrates a USB to serial chip, and it can be powered by a simple USB to micro USB cable. I also noticed a ESP8266 tutorial with NodeMCU firmware by SwitchDoc Labs the other day (using ESP-12 and Adafruit Huzzah), which I applied to my NodeMCU board, but since I encountered a few issues, I decided to report my findings, and write my own little getting started guide to switch on/off LED and GPIOs using a web interface. NodeMCU v0.9 and NodeMCU v1.0 If you are going to purchase a NodeMCU board it’s important to know there are two official versions: NodeMCU v0.9 with ESP-12 module NodeMCU v1.0 with ESP-12E module The main complain about NodeMCU v0.9 is that while it fits on […]

$47 Beelink MINI MX Android 5.1 TV Box Features Amlogic S905 Processor

It really feels like Christmas is around the corner, as deals on new and existing products keep on coming. About two weeks ago, I noted one of the first TV boxes based on Amlogic S905 processor, MXQ Pro, was starting (pre-)selling for as low as $48. Not bad for a device that is supporting HDMI 2.0 and 10-bit HEVC up to 4K @ 60 fps. Since then the price has gone up a little to $52 shipped, but Beelink MINI MX has started to up show up on a few sites, and the device is pre-sold for $46.89 on GearBest with GBMINIX coupon. The case is very similar to Allwinner H3 based Beelink X2, and the specifications similar to the ones for MXQ Pro: SoC –  Amlogic S905 quad core ARM Cortex-A53 @ up to 2.0GHz with  penta-core Mali-450MP GPU @ 750 MHz System Memory – 1GB DDR3 Storage – […]

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 […]

Element14 and Raspberry Pi Trading Launch a Raspberry Pi Customization Service

While the Raspberry Pi Foundation is the main face of the Raspberry Pi board, it only mainly promotes children’s education, and a subsidiary called Raspberry Pi Trading, funded in 2013, handles design, manufacturing and distribution of the Raspberry Pi boards, and puts profits back into the charity. Raspberry Pi Trading has now partnered with Element14 to offer customization services for the Raspberry Pi board. That means you’ll be able to remove or add interfaces and headers, replace the micro SD by a more reliable eMMC flash, add new functionalities to the board, and even re-design the layout in order to better match your project’s requirements. The companies “expect order quantities to start in the region of between 3,000 and 5,000 depending upon the nature of the customization”, so the service does not seem to be available , or cost effective, for smaller orders for a few hundred units. Element14 has […]

Low Cost 15.6″ Portable DVD Player Could Be Used as a Cheap Battery Powered HDMI Display

I’ve already written about portable displays with products such as Gechic On-Lap Monitors which sells for $200 and AOC USB Portable monitors are also popular, and somewhat cheaper than I expected at $120 and $199 for a 15.6″ display at respectively 1366×768 and 1920×1080 resolution, although if you live outside the US, shipping and import fees deposit bring the price much higher. A search for “portable display” on Aliexpress only showed some smaller 3.5 to 7″ displays, but I’ve been tipped about a 15.6″ portable DVD player selling for $114.53 on Chinavasion that could be used as an external display too thanks to its HDMI input. Specifications of this portable DVD player: SoC – Mediatek Solution Display – 15.6″ TFT LED Screen with 270 degree swivel; 1366×768 resolution; 16:9 aspect ratio Disc support – DVD, CD, EVD, VCD, CD-RW, DVD-R. Hitachi lens Video Output – AV Video Input – HDMI, […]
