ESP-07S ESP8266 Serial Wi-Fi Transceiver Module + 2.4GHz PCB Antenna
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 an upgraded and improved version of ESP-07 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. Solder it to the ESP-07 adapter board and then it can be plugged directly into a breadboard or PCB experiment board. Features: - Compatible with pin pitch and pinout of ESP-07 - 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: 4M 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. About the PCB antenna: - Suitable for ESP8266 series serial wifi wireless module such as ESP-02 / ESP-05 / ESP-07 / ESP-07S - Frequency: 2.1G - 2.5GHz - Antenna gain: 4dBi - S.W.R <= 2.0 @ 2100 MHz ~ 2500 MHz - Output Impedance: 50 Ohm - Extension cable interface: IPEX
