Description

This ultra-compact ESP-01S microcontroller module adopts 32-bit ESP8266EX processing core, equipped with 8 external pins and rich built-in communication interfaces including SDIO, SPI, UART, I2C, I2S, PWM and GPIO. It supports adjustable CPU clock frequency from 80MHz to 160MHz, stable operating voltage of 3.0V-3.6V, and ultra-wide working temperature range of -40℃ ~ 125℃ to adapt to various harsh working environments. The overall dimension is only 24×14mm, which is easy to be embedded into small-sized equipment. It supports multiple independent working modes and dual concurrent operation modes, widely applied in electronic prototype development, school STEM teaching, sensor data acquisition and small embedded automatic control equipment.
