Description
The DFRobot TEL0126 Gravity WiFi IoTInternet Of Things Module has an integrated TCP/IPTCP/IP is a suite of internet communication protocols. TCP (Transmission Control Protocol) is responsible for establishing reliable, ordered data delivery, and handling congestion control, while IP (Internet Protocol) focuses on routing packets of data to their destination. protocol stack that can give your microcontroller access to your WiFi network. The current version of this board comes with an ESP32-D0WD-V3 SoCSystem On a Chip (Datasheet) with 2.4GHz WiFi (802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n) and Bluetooth (v4.2 BRBasic Rate/EDREnhanced Data Rate and BLEBluetooth Low Energy) on a PCBPrinted Circuit Board with a Winbond W25Q32JV 4MB SPISerial Peripheral Interface Flash memory chip, 5V to 3.3V level shifting circuitry, 3.3V regulator, and a switchable UARTUniversal Asynchronous Receiver-Transmitter/I2CInter-Integrated Circuit.

| Security | WPAWi-Fi Protected Access (WPA) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WPA was released in 2003 as a replacement to the increasingly apparent vulnerabilities of the WEP standard. WPA2Wi-Fi Protected Access 2 (WPA2) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WPA2 was released in 2004 as a replacement of WPA./WPA2-PSKWi-Fi Protected Access 2 Pre-Shared-Key or WPA2-Personal (WPA2-PSK) is an encryption security protocol for 802.11 wireless networks to protect network access and data transmission by using an AES (Advanced Encryption Standard) or TKIP (Temporal Key Integrity Protocol) encryption method. It is designed for home users and small offices to protect their network without an enterprise authentication server. |
