• Operating Voltage3.3V

• 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

• Compatible with Arduino, MicroPython; Default firmware: lastest MicroPython

1. This module requires a 3.3 volt supply for VCC and 3.3V logic.
2. It is not 5V tolerant, 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
4. The 3.3V supply on the Arduino Uno has the inadequate current capability to power this module.
5. You must provide a separate, higher amp 3.3V supply(about 300mA or better)
