esp8266 v7 datasheet nc - XoilacTV

ESP8266EX implements TCP/IP, the full 802.11 b/g/n/e/i WLAN MAC protocol and Wi-Fi Direct specification. It supports not only basic service set (BSS) operations under the distributed control function (DCF), but also P2P group operation compliant with the latest Wi-Fi P2P protocol.

This document provides introduction to the interfaces integrated on ESP8266. Functional overview, parameter configuration, function description, application demos and other

The ESP8266MOD integrates antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. The compact design minimizes the PCB size and requires minimal external circuitries.

The ESP8266 Datasheet has a Pin 5 labelled as VDD_RTC and it describes its function as "NC (1.1V)". I usually understand NC to mean no connection on most ICs, or on relays as normally closed. Neit...
