ESP-12F ESP8266 Serial Wireless WIFI Module
A complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
WIFI Wireless Transceiver Module
Supports 3 modes: AP,STA,AP+STA
Pad spacing: 2mm
High quality module
High efficiency AT commands, simple for your development.
Important note: this is a 3.3v module, ensure it is only connected to the 3v lines on your micro-controller, direct 5v will damage the module.
In addition to the 3.3v power supply for the module, 5v TTL data lines also need to be shifted to 3.3v. When using the module with a 5V micro-controller, such as a standard Arduino, ensure to use a level shifter on the URXD pin – a simple resistor-zener level shifter or voltage divider is sufficient. Again, this is to prevent over-voltage.
Dimensions: 24mm x 16mm
