Barkirina standard a belaş ji bo fermanên zêdetir ji $9.9
Polîtîkaya vegerê
Tiştên vegerê dê di nav 40 rojan de were qebûl kirin dema ku roja wergirtina malê ye. Tiştên xweser nayên vegerandin an guhertin. Tiştên ku bi karta diyariya elektronîkî hatine kirin tenê dikarin were guhertin; veger nayê sepandin.
Diyariya belaş
Bi xêr hatî Roymall, malpera weya pîşeyî ji bo kirîna diyariyên depoya departmanê ya premium. Em piştgirî û qedirgirîya we bilind dikin û em dixwazin spasiya xwe bi zêdekirina hêvîya kêfê ya kirînên we nîşan bidin. Dema ku hûn li vir dikirin, hûn ne tenê hilberên kalîteya bilind ên ku jiyana we baştir dikin bistînin, lê hûn ê diyariyek belaş a taybetî jî bi her fermanê bistînin. Amade ne ku koleksiyona me vedikin û diyariyên we yên bêkêmasî bibînin? Di navbijartina me ya hilberên depoya departmanê ya premium bigerin, fermanê bidin û paşê li benda diyariya belaş a we ya bi kirîna we re were.
Polîtîkaya barkirinê
Em ê piştî wergirtina fermanên we ji bo şandina tiştan bi xebatê bigirin û pê ewle bin ku ew bi ewlehî têne. Agahiyên şandinê dê di e-nameya weya pejirandinê de were dayîn.Di piraniya rewşan de, ferman di nav 2 rojan de têne sepandin.Di şert û mercên taybetî de, wê wiha dereng bibin: Dema ku hûn fermanê di şemî, yekşem an jî înên giştî de bidin, dê 2 roj dereng bibin.Normal, ew hewce dike 5-7 rojên kar (ji duşemê heta înê) bêyî ku ji hêla derengiya firînê an faktorên din yên hawîrdorê ve were bandor kirin.Ji ber ku karûbara meya şandinê li seranserê cîhanê ye, ji ber vê yekê dema şandinê dê li gor cihê we be, ji ber vê yekê heke hûn li navçeyên dûr an welatan in, hûn hewce ne ku hinekî bisekinin.
1. Polîtîkaya Vegerê & Guhertinê
Em tenê tiştên ku ji roymall.com hatine kirin qebûl dikin. Heke hûn ji belavkerên me yên herêmî an firoşgehên din bikirin, hûn nikarin wan li vir vegerînin.Tiştên firotanê yên dawî an diyariyên belaş ji bo vegerê nayên qebûl kirin.Ji bo mafdarî ji bo vegerê, tişta we divê nehatiye bikar anîn û di heman rewşê de be ku hûn wê wergirtiye. Divê ew di pakêta xweya orîjînal de jî be.Piştî ku hûn rêwerzên vegerê ji me wergirtin, ji kerema xwe tiştên xwe yên vegerandî pakêj bikin û pakêta xwe li postexaneya herêmî an kuryeyek din bihêlin.Em ê tiştên we yên vegerandî an guhartî di nav 3-5 rojên karkirinê de piştî ku em wê wergirin, bisekinin. Veger dê bixweber li ser rêbaza weya orîjînal a dayînê were kredî kirin.Tiştên ku bi awayekî xweser hatine çêkirin, di nav de mezinahiya xweser, rengê xweser, an çapa xweser, nayên vegerandin an guhertin.Heke hûn hewceyê alîkariyê bin, ji kerema xwe bi me re têkilî daynin. service@roymall.com an Whatsapp: +447549870296
2.Polîtîkaya Vegerê
Hûn ê piştî ku em pakêta vegerandî wergirin û kontrol bikin, vegerê tevahî an 100% krediya dikanê bistînin. Veger dê bixweber li ser rêbaza weya orîjînal a dayînê were kredî kirin.Ji kerema xwe bînin ku lêçûnên barkirinê û her qebzeyek an xerc nayê vegerandin. Lêçûnên zêde yên barkirinê piştî ku pakêt hat şandin, nayê vegerandin. Hûn berpirsiyar in ku hûn van lêçûnan bidin û em nikarin wan bêpar bikin an vegerînin, heta ku ferman ji me re were vegerandin.Heke pirsgirêkek bi prosesa vegerê hebe, ji kerema xwe bi me re têkilî daynin. service@roymall.com an Whatsapp: +447549870296

Greatly speed up your IOT application developing process.
Lowest cost WI-FI
It is a tiny board, based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board
Package Included:
1/3/5/10/20 x NodeMcu Lua CH340G ESP8266 WIFI Internet Module (optional)
Fantastic quality board for a fantastic price. I already had the CH340 USB driver installed for a different board so the NodeMCU worked right away with Arduino IDE. There are 3 main ways to use this:
- Program it using Lua, I believe the firmware it comes with supports this although I didn't try it.
- Write code for it in Arduino IDE (C++). This is the most flexible and highest-performance option, and gives you access to extensive libraries available in Arduino IDE with one button click. Environment is very similar to coding for Arduino.
- Use it as a "dumb" WiFi peripheral with AT commands sent over the serial port from another CPU (Hayes modem style). The firmware you need to load for this is fairly easily found on the web.
Note that it's wider than some other NodeMCU boards so it doesn't leave any connection points available beside it when on a standard project board, but this is easily solved using some non-stranded hookup wire connected underneath.

Q:
Hello, is this NodeMcu ESP8266 ESP-12F or ESP-12E?
olá, está placa é o NodeMcu ESP8266 ESP-12F ou ESP-12E ?
Arduino ide doesn't automatically have this board. You have to add it.
You need to open Arduino IDE, choose File-->Preferences and then add this URL: ***** into the section that says: Additional Boards Manager (urls), save or OK, Then you have to go to Tools--> Boards Manager and add 8266 to the list of boards.
If you are not sure, try this step by step tutorial at *****

Q:
Are the data pins 3.3v or 5v tolerant? Clearly the board accepts 5v, and there is a voltage regulator to drop the supplied voltage to 3.3v - my understanding is that the ESP8266 is only 3.3v tolerant - so if you supply 5v to VIN do the data pins only provide 3.3v? Can you interface 5v I2C modules to this device, or only 3.3v I2C modules?

Is this module compatible with the Geekcreit UNO R3 ?

I cannot boot nodemcu from Vin with voltage of 5 volts. The dev board only boot from USB. Can you please tell me how to power the unit without using the usb?

Wasn't able to edit my previous question so here is the modified question:This is not the same as previous V3. Pin Rows are wider: 1.1in vs 0.9in and there was a LED on the board connected to D0 that doesn't seem to exist. The ESP8266 Wifi chip seems to run warmer than the previous V3 but is much cooler than the super hot V4. The builtin LED seems to be controlled by GPIO 02 (D4) and not GPIO 16 (D0). It has Ver 0.1 marked on the board near D0. If this is really a V3 devkit, how many different versions are available?

You have to enter the ssid and password to your WiFi in your code. The device will then connect to the network you specified. Look at example code to see how it's done
