Konke Mini K and Mini Pro Wifi Smart Sockets are Based on ESP8266 SoC

ESP8266 WiFi modules are very popular in the maker community, but so far I have not seen it in any devices myself, until I saw a tweet from @EspressifSystem about a Mini K smart socket. A search on Aliexpress lead me to two devices made by Konke, who also made Kankun KK-SP3 WiFi socket, with Mini K and Mini Pro smart sockets. Both models has basically the same features, except Mini-Pro adds infrared support: Connectivity – 802.11 b/g/n Rated Voltage – AC 100-240V 50/60Hz Rated Power – 2200 Watts Rated Current – 10A Charging Protection: Yes Misc – Power button, Infrared (Mini Pro model only) Plug – China / AU plugs Dimensions – 5.1 diameter x 2.7 cm (V0 grade PC material) Weight – 70 grams Both devices support on/off timers, cyclical delays and charge protection (turns off when devices are charged) with the Android or iOS app. I understand […]

$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 […]
