    Product as description. Tested ok working as expected. AT comands firmware preloaded. I suppose micropython or other sketch can be used. Tested as it is to control a led or a relay through a web page. good product. Reccomend.

    To use the ESP01 with 5 volt, use an adaptor, see "Geekcreit® ESP8266 Serial Wi-Fi Wireless ESP-01 Adapter Module 3.3V 5V". This adapter is very handy. It has a voltage converter (5V to 3.3V) and level converters on board. When using the ESP01 with a temperature/humidity sensor (for example DHT22) I noticed that the 3.3V is sometimes too low for the DHT22. Reading is not stable. But there is a nice trick, to let the DHT22 work on 5 Volt! Use the TX pin at the adapter(!), for which the "level is converted"

    Lo mas barato que puedes usar para comunicar tus microprocesadores por wifi, el modulo viene empacado en su empaque antiestatico sellado, y es muy fácil de programar, el uso por comandos AT te funciona para comunicación serial y si decides re-programarlo como sketch de arduino te permite usarlo para activar un relay sin la necesidad de usar la placa de arduino, perfecto para controlar equipos via wifi.

    I need this devices to connect my Arduino Uno to Internet, works perfect with serial port, need to set the speed to 9600 baudios, but with a simple AT Command, is easy to setup.

    Brilliant little chip for those simple switching devices or for data transfer over serial. Connects to standard BGN wifi. Easy to interface arduino or other similar microcontroller.

    haven't tasted it yet. Not breadboard friendly but these tiny device can do a lot
