We are pleased to inform that our boards and modules have been used during course “Internet of Things” at the WSB University in Wroclaw (Poland, UE). Students learned about the ability to build and programing “Smart Home” using the Electrodragon Relay boards, modules, various sensors, and LEDs and displays. PlatformiIO was used for example programming.
ESP3212 board based on ESP32 IC will be ready on around 20th, this is the date we asked from supplier ai-thinker, they said they are still debugging the board, date can not guarantee, maybe delay again. We will sell the same price as anywhere else. Most information we can find are placed on this page now.
Thanks to customer Mark, here is wiring diagram of the flow sensor/meter with esp8266, the key point is needing a 555 timer chip as a Schmitt trigger. Also the VCC voltage of flow sensor is 5V, and esp8266 is 3v3, a voltage divider is needed in the circuit. You can find the flow sensor here. Updated to
It seems the current online custom build with dev branch can not work well with smartconfig, or the ESP8266 smart config android APK, so we tried to figure with the espressif official APK and master branch. The master branch is: Build on ESP8266 NONOS SDK 1.4.0, support ESPTouch 0.3.4.3 Dev branch version is Espressif NONOS SDK
You can find the mentioned items in our store here. This is a demo test of the pair of wireless power charger, five LEDs connected paralleled on the receiver end, output more than 200~300 mA (over range of display) current. There are some more notes: We use a very thin plastic bag to separated the receiver
Pick and place file output from eagle, and copy into a SD card for use. The machine only running 10% speed of normal, but actually it can run 150% speed of normal. Each time pick and place work include the following steps: Move to the PCB 0,0 (x,y) zero point, which is locate on the
Shipment Suspend: We will have a long holiday from 4th till 13th, delivery can not be fulfilled during this time. Holiday promotion: Use coupon code “2016-year” to get 10% discount. This discount is not conflicting with your member discount. PCB service PCB service will restart on 14th, please notice. If you place PCB order now, we will
A simple breakout board of ESP8266 on breadboard can do most of NodeMCU work. Also need a PL2303 USB-TTL programmer Most wifi embedded project will not have too much input and output resource to let the user enter the wifi SSID and password info, so we normally config this via phone app. This is the
All the relevant items can be purchased from www.electrodragon.com! items used in here including: ESP-07 with on board status LED (ESP-12 LED will not work for arduino blink sketch) ESP breakout board CH340 USB-TTL programmer breadboard and a few jumper wires. You can find the flash tool on this page. Flashing options in the tool explained
You can find the arduino library in the product link: http://www.electrodragon.com/product/ws2812-neopixels-ring-leds/ http://www.electrodragon.com/product/8-led-ws2812-5050-rgb-led-stick-board/ From the example, run “standtest” sketch, follow the instruction to setup for the board, and it will show all the standard effects: The wiring should be Din – pin6 of arduino, VIN – 5V arduino, GND – GND arduino.
