ESP-07 ESP8266 Wifi Module module allows any microcontroller to connect to an 802.11b/g/n wireless network. This in turn provides your microcontroller project with the ability to request data from a server anywhere in the world 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 (115200 baud default) commands. The ESP8266-07 also features an onboard ceramic antenna as well as a uFL connector allowing an external antenna to be connected (see item HCWILS0001).
Please Note: This module operates at 3.3V only. If interfacing to a 5V microcontroller level shifters should be used. For a suitable USB adapter see item HCMODU0051 Silicon Labs CP2102 3.3V USB to UART Serial Interface module.
