Overview
The LILYGO TO-ESP8266 OLED SH1106 is a compact development board pairing the ESP8266 WiFi SoC with a 1.3-inch SH1106 OLED display. Operating at 80MHz or 160MHz, the ESP8266 provides WiFi 802.11 b/g/n connectivity with 8 digital I/O pins and one analog input (max 3.2V). The SH1106 OLED connects via I2C (SDA on D1, SCL on D2) and delivers a sharp monochrome display ideal for sensor readouts and status screens. The board includes a CH9102 USB-to-serial bridge, a 1.25mm JST 2-pin battery connector for LiPo power, and three configurable buttons (D6, D7, D8). It is fully compatible with ESPHome and Tasmota, making it an accessible entry point for WiFi-connected smart home displays and environmental monitor nodes.
