ESP8266 Wifi Module ESP-07 For Arduino UNO WIFI Transceiver Wireless Esp-07 AP+STA WiFi Board Panel 3.3V 300mA
Model: ESP8266 ESP-07
Semi-hole chip technology, all the IO leads, with metal shielding
shell, external IPX antenna, built-in ceramic antenna can also be used
This module requires a 3.3 volt supply for VCC, and 3.3V logic.
It is not 5V tolant,Connect RX or TX on 5V FOR Arduino will destroy this module.3.You must use a logic level converter, or a 3.3V FOR Arduino
The 3.3V supply on the FOR Arduino Uno has inadequate current capabilit to power this module.
You must provide a separate,higher 3.3V supply(about 300mA or better)
