The ESP32-WROOM-32 NodeMCU board provides 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 up to 150Mbps with
APA WiFi Access Point (AP) is a device that creates a wireless local area network, or WLAN, and acts as a central hub that allows other devices, such as smartphones or computers, to connect to it over WiFi./STAA WiFi Station (STA) is a device that has the capability to connect to an existing WiFi network as a client in the same way other devices, such as smartphones or computers, join an established network and communicate with other devices on that network or access the internet./AP+STAA WiFi device in AP+STA mode acts as both an Access Point (AP) as well as a Station (STA), where the device can connect to an existing network as a client (STA) while simultaneously hosting its own network (AP) for other devices to connect to.

antenna.
Revisions of the ESP32-WROOM-32 module, such as the
ESP32-WROOM-32D and ESP32-WROOM-32E, are also commonly
found in the ESP32 NodeMCU board. Each revision has a different chip inside the module, but they are all compatible.
The ESP32-WROOM-32 module contains an ESP32-D0WDQ6 SoC.
The ESP32-WROOM-32D is a revision of the ESP-WROOM-32
module which uses a ESP32-D0WD chip with a smaller footprint.
The ESP32-WROOM-32E module is a direct upgrade to the
ESP32-WROOM-32D that fixes some bugs with a new chip version
ESP32-D0WD-V3 or ESP32-D0WDR2-V3.
