SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
NodeMCU DEVKIT 1.0, bottom. NodeMCU is a low-cost open source IoT platform. [4] [5] It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.
It runs on ESP8266 [2] Wi-Fi based MCU (microcontroller unit) platforms for IoT from Espressif Systems. The name "ESP Easy," by default, refers to the firmware rather than the hardware on which it runs. [3] [4] At a low level, the ESP Easy firmware works the same as the NodeMCU firmware and also provides a very simple operating system on the ...

A Wi-Fi device is a short-range wireless device. Wi-Fi devices are fabricated on RF CMOS integrated circuit chips. [127] Since the early 2000s, manufacturers are building wireless network adapters into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in ever more devices. [128]
The more complex kind has a built-in modem to connect to the internet without needing another device. [2] This converged device saves desk space and simplifies wiring by replacing two electronic packages with one. It has a wired connection to the ISP, at least one jack port for the LAN (usually four jacks), and an antenna for wireless users.
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.
Wi-Fi Direct devices can connect to a notebook computer that plays the role of a software Access Point (AP). The notebook computer can then provide Internet access to the Wi-Fi Direct-enabled devices without a Wi-Fi AP. Marvell Technology Group, [14] Atheros, Broadcom, Intel, Ralink, and Realtek announced their first products in October 2010. [15]
