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. Note:   This module requires a 3.3V supply for VCC, and 3.3V logic. It is not 5V tolerant. Connecting Rx or Tx on 5V Arduino may destroy this module. You must use a logic level converter, or a 3.3V Arduino. Also the 3.3V supply on the Arduino Uno has inadequate current capability to power this module. You must provide a separate, higher 3.3V supply (about 300mA or better)   Features ESP serial wifi: ·         SDIO 2.0, SPI, UART ·         Integrated RF switch, balun, 24dBm PA, DCXO, and PMU ·         Integrated RISC processor, on-chip memory and external memory interfaces ·         Integrated MAC/baseband processors ·         Quality of Service management ·         I2S interface for high fidelity audio applications ·         On-chip low-dropout linear regulators for all internal supplies ·         Proprietary spurious-free clock generation architecture ·         Integrated WEP, TKIP, AES, and WAPI engines   Specification ESPEX: ·             b/g/n ·             Wi-Fi Direct (P2P), soft-AP ·             Integrated TCP/IP protocol stack ·             Integrated TR switch, balun, LNA, power amplifier and matching network ·             Integrated PLLs, regulators, DCXO and power management units ·             +19.5dBm output power
