    Product as description. Tested ok working as expected. Arrived well packed. The development board and data cable in a plastic box and oled in another smaller plastic box. Lately few items ordered arrived in a lower protection packages - only a small plastic bag inside a bigger plastic bag with no bubble foil - and some delicate items like oled display I found broken. This time the package was the proper one and everything came unharmed. Good quality product. Reccomend.

    Item delivered on time. I marked the pins for the OLED display and the DHT11 sensor on the photos added to this review. After few tests I noticed that the DHT11 started giving me some bad reading values, so I replaced with a DHT22 sensor. I'm using this ESP8266 to publish data via MQTT.

    Working great! Used example 10 in the downloads for DHT11 sensor and OLED and was able to get started off with that.

    Ordered this for playing around with Arduino IDE. code examples not suitable so had to figure this out myself. To save you the hassle, see included screengrab of the code that works! as a target i'm using the LOLIN(WEMOS) D1 r2 & mini for libraries: DHT and U8g2 changed pinout to suitable pins and it works a charm. SHowing temp and humidity on display as you'd like. Can develop further from here using the many ESP8266 libraries.

    It came in a nice plastic box, looks god and valued. I did not tried out but I have other sensor in mind to connect to the board.

    My first project but did not understand the provided code files that code be download. I wanted to use the Arduino IDE and not the software provided. This is how i did it https://www.youtube.com/channel/UC_OWU7bJNQypa0LTScMtrrw I am new to coding but making good progress. Loads to learn from this small project. I hope my videos will help somebody else get started

    This is a really good package. The DHT and the I2C screen can be taken off and used separately. The development board works very well as a stand alone ESP-8266 device. The screen is wired to GPIO2(SDA) and GPIO14(SCL) and not to GPIO4 and GPIO5. You have to make sure that your program uses these pins. Sketches that worked with the screen have contained: SSD1306Wire display(0x3c, SDA, SCL); Wire.begin(2,14);

    Here is a sample program which shows the temperature and humidity at the display and on the serial port as well #include #include #include #include DHTesp dht; #define SCREEN_WIDTH 128 // OLED display width, in pixels #define SCREEN_HEIGHT 64 // OLED display height, in pixels // Declaration for an SSD1306 display connected to I2C (SDA, SCL pins) Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1); void setup() { Serial.begin(115200); Serial.println("\n\nThe board name
