    Product as description. Tested ok working as expected. Lately many orders from this seller are very poor packed in terms of protection during transit. Only the antistatic bag inside a thin plastic bag and inside a bigger plastic envelope. There is no bubble foil to protect the fragile items inside eg. oled lcd and these can be easily damaged by the rough handling during transport. In short term this procedure can save money for seller but it is a trap because in long term the customers will start avoid to buy from this seller due to high rate of dead on arrival products. Good quality board. Recommend.

    This Arduino compatible board is a nice addition to my collection and it comes with a few unique features. Being based on the ESP8266 platform, naturally there's WiFi on board. No need for a WiFi shield. My board features the ESP-12S. There's 4MB of flash, which makes OTA updating work like a charm. The only thing missing as compared to a genuino Arduino, is more than one analog input. If your project needs that, look for another board, but if you only do digital input/output, this could be the board for you.

    If you are interested in micro contollers you should give this one a try. There are a lot of instructions available in the web and on youtube. This is not just an Arduino shield. This one is based on a ESP-8266 WiFi module and has the Arduino Uno shape only. But you can program it with the Arduino IDE just by downloading the ESP-8266 extensions. The generated code is quite big, therefore even uploading simple projects takes a wile. I you are used to Arduino already it is quite easy to compile and upload the WebServer example.

    This board is eons better than any Arduino board. It has built-in WIFI! Nothing is better than this. WIFI can be used both as Station and as Access Point. Additionally at the same time! It can be programmed using the Arduino IDE. If you're using time-critical methods, make sure you'll use "delay()" oder "yield()" in it. Otherwise the Wifi-connection could be cut off and/or you can't program your board anymore (You have to set it in the programming mode manually). There is no documentation about the functions that are available (with description and so on) like in for the Arduino boards. If you want to use SD-Card-boards, you´ll have to copy a part of the built-in SD library to the one delivered with the arduino IDE or delete this one. This board is really better than any Arduino board, but has only 1 (!) analog pin. In future, you could use the ESP 32. It is better than the ESP 8266.

    this WEMOS D1 board is very well manufactured and works very well with Linux Mint. Take care about the CH340 chipset if used with different operating systems. I suggest to check on internet the instructions for setting the parameters if you have difficulties in having the proper communication with your computer. It is also necessary to follow the correct procedures for installing the esp8266 information on the Arduino IDE before using it or the system cannot recognize the board. It is a very good value for money. a must have for every Arduino enthusiast Questa scheda WEMOS D1 è molto ben prodotta e funziona molto bene con Linux Mint. Prestare attenzione al chipset CH340 se utilizzato con diversi sistemi operativi. Suggerisco di controllare su Internet le istruzioni per l'impostazione dei parametri se si hanno difficoltà ad avere la corretta comunicazione con il computer. È inoltre necessario seguire le procedure corrette per l'installazione delle informazioni esp8266 sull'IDE di Arduino prima di utilizzarlo o il sistema non è in grado di riconoscere la scheda. Ottimo rapporto qualità / prezzo. un must per tutti gli appassionati di Arduino
