WiFi ESP8266-12-S Serial TTL Module

Description

Overview The ESP-12S is a WiFi module based on ESP8266, with built-in 32Mbit Flash, in the small SMD16 package. There’re also onboard PCB antenna and metal shield. In short, it’s a small form factor and fairly high cost effective WiFi module. With the pre-flashed AT firmware, you can control the module through UART AT commands easily. The module integrates MCU inside, supports other developments like Lua/Micropython/Arduino to achieve flexible and fast prototyping, make it easy to integrate the module into IoT applications. Features 802.11b/g/n Wi-Fi SOC Integrated Tensilica L106 ultra-low-power 32-bit micro MCU, run at 80 MHz and 160 MHz frequency, supports RTOS Built-in 1-ch 10 bit high precision ADC Supports UART/GPIO/ADC/PWM/I2C SMD16 package Integrated Wi-Fi MAC/ BB/RF/PA/LNA Supports multi sleep modes, deep sleep current as low as 20uA UART baud rate up to 4Mbps Embedded Lwip protocol stack Supports STA/AP/STA+AP operation mode Supports Smart Config (APP) / AirKiss (WeChat), one key networking Supports UART local firmware upgrade and/or remote firmware upgrade (FOTA) AT commands for getting started fast Supports secondary development, integrated Windows / Linux environment Specification: Module Model ESP-12S WIFI chip ESP8266 Built-in Flash 32Mbit Package SMD16 Antenna Onboard PCB antenna Frequency range 2.4G ~ 2.5G (2400M ~ 2483.5M) WIFI protocol 802.11b/g/n WiFi WIFI mode STA, AP, STA+AP Security WPA / WPA2 Encryption WEP / TKIP / AES Firmware upgrade UART / OTA Trans
