ESP-12 (ESP8266) wireless WIFI transceiver

Description

This amazingly priced wireless module allows any microcontroller to connect to a 802.11b/g/n wireless network. This in turn provides your microcontroller project with the ability or request data from a server anywhere in the word via a suitable WiFI connection. Control of the module couldn't be simpler as it comes pre-flashed with a serial application allowing it to be controlled via simple 'AT' serial (9600 baud default) commands. Please Note: This module operates at 3.3V only. If interfacing to a 5V microcontroller level shifters should be used. SKU: HCMODU0077 Module: ESP-12 Device: ESP8266MOD Frequency: (ISM): 2.4GHz Power: +25dBm Supported Wifi: 802.11 b/g/n Operating voltage: 3.3V Min Current (Sleep): 10mA Max current (connected to 802.11b network): 215mA VCC.........3.3V GND........0V CH_PD.....Power down pin. Connect to 3.3V for normal operation Additionally to configure the module to accept AT commands you should connect the following pins to GND/VCC GPIO0......VCC (HIGH) GPIO2......VCC (HIGH) GPIO15....GND (LOW) AT Commands, examples available on our support forum here .
