ESP8266 ESP-01S WiFi Serial Transceiver Module

ESP8266 ESP-01S WiFi Serial Transceiver Module The ESP8266 is the name of a micro controller designed by Espressif Systems. The ESP8266 itself is a self-contained WiFi networking solution offering as a bridge from existing micro controller to WiFi and is also capable of running self-contained applications. Description: comparing to ESP-01 (old version), ESP-01S (updated version) has these advantages: The PCB layout has changed for an improvement in WiFi radio performance 1MB Flash Memory?upgraded from 512KB Latest version esp-01s, with stronger signal Feature SDIO 2.0, SPI, UART Four pins interface, VCC-3V3, GND, TXD and RXD. Two extra GPIOs can use. AT commands firmware.
