With integrated TCP/IP protocol stack, this module lets your microcontroller interact with WiFi networks with only a few lines of code. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can send simple text commands to control the device. The SoC features integrated WEP, WPA/WPA2, TKIP, AES, and WAPI engines, can act as an access point with DHCP, can join existing WiFi networks and has configurable MAC and IP addresses. **FEATURES** Grove 4-pin connector (RX,TX,VCC,GND) 802.11 b/g/n protocol (2.4GHz) WiFi Direct (P2P), soft-AP Supports three modes: AP, STA and AP+STA coexistence mode Integrated TCP/IP protocol stack LwIP (lightweight IP) Integrated low power 32-bit CPU could be reprogrammed as an application processor Integrated temperature sensor Serial UART Interface Multi-queue QoS management Wake up and transmit packets in
