Wi-Fi dev board with a built-in 0.96" OLED — no wiring needed for your first connected display
This board combines the well-known ESP8266 (ESP-12E) Wi-Fi microcontroller with an on-board 0.96-inch OLED, so the usual first hurdle — wiring a display to the right I2C pins without loose contacts — disappears completely. The display is a 128 × 64 SSD1306 panel, supported by every Arduino and MicroPython display library. The ESP8266 gives you 2.4 GHz Wi-Fi, 4 MB of flash, 80 MHz clock and 16 digital I/O pins for your sensors. Classic uses: internet weather station, crypto/stock ticker, network monitor, desk clock. Header pins ship loose for breadboard mounting.
