$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 […]

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 […]

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 […]

$24 Wall Socket Router Includes WiFi, Ethernet, USB, and a Phone Jack

There are already several small routers or repeater that you can connect to a wall socket, but that’s not what I’m taking about here, as I’ve been informed about a wall socket, or gang box, being the router itself. It supports 802.11 b/g/n WiFi, and features two RJ45 Ethernet ports, an RJ11 phone jack, and a USB port for 3G dongle or charging mobile devices. “In-color” wall router specifications and features: SoC, memory and storage – Unknown Connectivity 802.11 b/g/n with support for WiFi relay, WiFi hotspot 2x Ethernet LAN ports (external), 1x Ethernet WAN port (internal) RJ11 phone jack USB – USB port up to 5V/2A for charging, USB mass storage, or a 3G USB dongle Misc – Power on/off button for USB port?, two terminal blocks for mains and phone line. Power Supply – AC 110V-240V or PoE The product description also mentions the router supports cloud storage, […]

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 […]
