ESP8266 ESP-01 ESP01 Serial Wireless Wi-Fi Module Transceiver Receiver Board LWIP AP+STA for Arduino DIY Kit black

Description Condition: NewBrand Name: HESAI Type: Voltage Regulator   Descriptions: ESP8266 is a highly integrated chip designed for the needs of a new connected world. It provides a complete and self-contained Wifi networking solution, which allows either host application or to offload all Wifi networking features from another application processor. ESP8266 has powerful board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up front and minimal load during runtime. Its high level of chip integration allows for minimal external circuits, and the entire solution, including front-end module, is designed to occupy minimal PCB area.  Inductions:SDIO 2.0, SPI, UART     32-pin qfn     Integrated RF switch, balun, 24dBm PA, DCXO, and PMU     Integrated RISC processor, on chip memory and external memory interfaces     Integrated / baseband processors     Quality of service management     I2S interface for high fidelity audio applications     On chip low dropout regulators for all internal deliveries     Proprietary spurious-free clock generation architecture     Integrated WEP, TKIP, AES, and WAPI engines     Solutions     Supports APSD for optimal VoIP applications     Patented spurious noise cancellation algorithm for integration into SOC applications     Supports Bluetooth co-existence interface     Self calibrated RF for optimal performance under all conditions     Zero factory tuning     No external RF components  Features:802.11 b / g / n    Wi-Fi Direct (P2P), Soft-AP    Integrated TCP protocol stack    Integrated TR switch, balun, LNA, power amplifier and matching network    Integrated PLLs, regulators, DCXO and power management units    + 19.5dBm output power in 802.11b mode    Power down leakage current of
