ESP-01S ESP8266 Serial Wi-Fi Wireless Module + Adapter for Arduino
This is WiFi serial transceiver module£¬ based on ESP8266 SoC which has integrated TCP/IP protocol stack. It optimizes the filter circuit and reduces power consumption. It is compatible with ESP-01 and it is an upgraded and improved version of ESP-01 module. It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking£¬ smart home project when it is connected to the wifi router. It can be used for remote monitoring of home appliances£¬ bedroom temperature and humidity£¬ and controlling home appliances by the mobile phone. With the help of ESP-01 Adapter module£¬ it can be connected directly with the Arduino board and other 5V MCU development board. The Whole module features: - Arduino UNO R3 and the compatible board can directly connect to this module. - You can debug the module with the USB to TTL module£¬ such as FT232RL£¬ CH340G module. - Interface logic voltage: 3.3V / 5V compatible(On-board level shift circuit) - Working frequency: 2400 - 2484 MHz - Working voltage: 4.5V - 5.5V (On-board 3.3v LDO Regulator) - Working current: 240mA(MAX) - Serial port baud rate: 115200 (default)£¬ can be modified to other values ?by AT command - Serial communication format: 8N1 - Antenna Type: Built-in PCB antenna is available. - Wireless Network Mode: station / softAP / SoftAP + station - Wireless criteria: 802.11 b / g / n - WIFI @ 2.4 GHz£¬ support for WPA / WPA2 security mode - It is very easy to design projects by AT command - Applications: Home automation£¬ sensor networks£¬ industrial wireless control£¬ smart car.
