ESP8266 ESP-01S Serial WIFI Wireless Transceiver Module Send Receive AP+STA

Description:

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.

Features:

• Working frequency: 2400 - 2484 MHz
• Working voltage: 3.0 - 3.6VDC
• Working current: 200mA(MAX)
• Serial port baud rate: 115200 (default), can be modified to other values by AT command
• Serial communication format: 8N1
• On-board flash capacity: 1M bytes
• 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

Note:

When connecting with Arduino, you need to add 5V / 3.3V level converter circuit

Applications:

Home automation, sensor networks, industrial wireless control, smart car.
