ESP8266 is an inexpensive serial-to-wifi transceiver chip that can be used to connect any microcontroller with a serial port to a WiFi network. Because of its simplicity and low cost, it is getting popular among hobbyists for implementing it in Internet of Things (IoT) applications. ESP-01 module provides access to the power supply and I/O pins of ESP8266 through a 2x4 male header. But the pin arrangements are not user friendly.

 

This “ESP8266 ESP-01 Wifi Mini Development Board”  has a 6 Pins L-Shape Male header for Programming. Other 4 Pins are Yellow Male header for 3.3V, GND, GPIO2 and GPIO0. There’s also Flash and Reset Switch.   

 

Programmer:

Our FTDI USB to Serial Converter 3V3-5V (image 4) can be directly connected to it for programming the ESP8266 module.

Q: When open arduino serial monito,then show connecting ....... Can't show IP address Questioned by it.net.in, 12-Mar-2017

এটা 3.3V এ চলে। যদি আরডুইনোর সাথে ব্যাবহার করতে চান তাহলে আপনাকে আরডুইনোর Rx Pin কে 3.3 তে কনভার্ট করে নিতে হবে। Esp8266 Tx -----Arduino Tx Esp8266 Rx-----2.2K Reistor to GND -----1K Reistor to Arduino Rx Answered by Production, 14-Mar-2017 12:24 PM

Q: I have purchased this module few days ago and want to use with Arduino. Would you please help me providing the pin connection between this module and Anduino? Questioned by siddiquinoor, 21-May-2017

It's not needed. It has a stadalone microcontroller. However, please see in google. If you want to use arduino just as USB to TTL converter, please see the comment above. Answered by A.R, 22-May-2017 09:48 AM

Q: Today bought this product with a 3v3-5v FTDI USB to Serial. But not being able to upload simple blink code on to it. I have selected 3v3 jumper on FTDI. When I press (and continue) the flash button, green LED is lit and then press the reset button and release it then release the flash button as well. When I upload the sketch code, IDE compiles it fine but at last shows the errors: warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed What should I do now? Please advise... Questioned by mfq_khan, 20-Sep-2017

Q: ফোন ও মডিউল কি একই রাউটার / ওয়াইফাই এ কানেক্ট করতে হয়? আমি কি এই মডিউল দিয়ে ঢাকা থেকে চট্টগ্রামে লোড কন্ট্রোল করা যায়? Questioned by Tanmoy_Kumar_Ghosh, 11-Jul-2020

ইন্টারনেট ব্যবহারের মাধ্যমে নিয়ন্ত্রণ করতে চাইলে, যে কোন যায়গা থেকেই করা যাবে। ইন্টারনেট ছাড়া ব্যাতিত করলে ওয়াইফাইয়ের রেঞ্জ অনুযায়ী করা যাবে। সেক্ষেত্রে মোবাইল ও মডিউল একই রাউটারের অধীন কানেক্ট থাকতে হবে। Answered by Production, 11-Jul-2020 15:24 PM

Q: I am not able to find documentation about this module. can anyone provide this. I bought it few days ago and can't program it using Arduino uno, procedure and wiring information is very much required. Questioned by crowler70@gmail.com, 01-Dec-2022
