> 3 dayThe pins were not soldered perpendicular to the board making it impossible to insert into any kid of socket or breadboard. Very bad quality control if any.

11-06-2025Very easy to create a simple wifi-enabled application using the arduino IDE. Do note the limitation of using the ADC and wifi at the same time though -- if this is needed the ESP32 may be better

> 3 dayI must say this is a great board and runs Arduino well. My only issue at first is that the pin numbers are not correct / using the same format as Arduino. After a little digging, I found this on Github that maps out the difference. static const uint8_t D0 = 16; static const uint8_t D1 = 5; static const uint8_t D2 = 4; static const uint8_t D3 = 0; static const uint8_t D4 = 2; static const uint8_t D5 = 14; static const uint8_t D6 = 12; static const uint8_t D7 = 13; static const uint8_t D8 = 15; static const uint8_t D9 = 3; static const uint8_t D10 = 1;

> 3 dayThis may be a fine product, but support for it is horrible. Ive spent hours trying to get it to work. There are numerous postings of people trying to get it to work, but very little in the way of success. Save yourself a headache and avoid this product.

> 3 dayPretty disappointed with these boards. I foolishly ordered several thinking they would be as advertised. I quickly got the Arduino environment set up to program this board and ran blink within about 10 minutes. Everything came to a halt shortly after that. I tried to connect to my wifi without success. I have scoured the Internet for a solution to this problem without any luck. I now have four LED flashers.

> 3 dayThese boards do not connect with the Arduino IDE. I plug them in and never see a port - and Ive followed the instructions about downloading the esp drivers and software, etc. THE BOARDS DONT WORK! Save your money and get them from someone reputable like adafruit instead. Youll be much happier. These are a ripoff.
