ESP-WROOM-02 is the famous WiFi module from Espressif System, the company that produce ESP8266 WiFi chip. This the SMD version with FCC/CE/TELEC certification. This module is a highly integrated WiFi 802.11 b/g/n module that consumes extremely low power while providing a wireless internet connection for embedded devices. With a very small form factor (18mm by 20mm), this wireless module easily assimilates into resource limited devices. These features make it a great choice for OEMs to connect their IoT (Internet of Things) applications. ESP-WROOM-02 is a 32-bit low power micro-controller (MCU) that integrates with TCP/IP network stacks; the included 10-bit ACD interfaces with HSPI, SDIO, UART, PWM, I2C and I2S. Programs and firmware can be stored in the integrated SPI flash with 16Mbits (2MB) capacity. Features: 802.11 b/g/n Fast sleep/wake context switching Adaptive radio biasing Advance signal processing Integrated low power 32-bit MCU Built in SPI Flash: 16MBit, 2MB Integrated TCP/IP protocol stack Integrated TR switch, balun, LNA, power amplifier and matching network Integrated PLL, regulators and power management unit Supports security protocols WPA/WPA2 Supports Station / SoftAP / Station SoftAP operation modes Supports Tranmission Control Protocol (TCP) and User Datagram Protocol (UDP) Supports WiFi Protected Setup (WPS) for easy setup and configuration Supports mesh networking Supports Smart Link Function for both Android and iOS devices Supports Cloud Server Development Custom firmware development via SDK Download and write firmware via host User configuration via AT Instruction Set, Cloud Server and Android/iOs App FCC, CE and TELEC certified Specifications: Model: ESP-WROOM-02 Wireless Standard: IEEE 802.11b/g/n Frequency Range: 2.412GHz – 2.484GHz Hardware Interface: UART, I2C, PWM, GPIO, ADC, SPI Operating voltage: 3.0 – 3.6VDC Wireless Network Type: STA/AP/STA AP Security: WEP/WPA-PSK/WPA2-PSK Encryption: WEP64/WEP128/TKIP/AES Firmware Upgrade: UART or OTA Remote Upgrade Network Protocol: IPv4, TCP/UDP/FTP/HTTP Dimension: 18mm x 20mm x 3mm Antenna: 3dBi PCB on-board antenna Packing List: 1 x ESP-WROOM-02 WiFi Module (SMD) Category: ESP
