The Raspberry Pi 3 has included integrated 802.11 b/g/n wireless LAN, Bluetooth Classical and LE. You
didn't need additional peripherals to make it wireless. It is 10x the performance of Raspberry Pi 1.
What's more, it has complete compatibility with Raspberry Pi 2, which means almost all the previous
Raspberry Pi 2 accessories are compatible with Raspberry Pi 3.
The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in
Compared to the Raspberry Pi 2 it has:
A 1.2GHz 64-bit quad-core ARMv8 CPU
802.11n Wireless LAN
Bluetooth Low Energy (BLE)
Like the Pi 2, it also has:
4 USB ports
40 GPIO pins
Full HDMI port
Combined 3.5mm audio jack and composite video
Camera interface (CSI)
Display interface (DSI)
Micro SD card slot (now push-pull rather than push-push)

NodeMCU is an open source IoT platform.It uses the Lua scripting language. It is based on the eLua project, and built on the ESP8266 SDK 0.9.5. It uses many open source projects, such as lua-cjson,and spiffs. It includes firmware which runs on the ESP8266 Wi-Fi SoC, and hardwarewhich is based on the ESP-12 module.
2.5A is now a requirement for the Raspberry Pi 3. The CanaKit 2.5A Raspberry Pi power supply / adapter has been specially designed and tested for the new Raspberry Pi 3 and incorporates an inline noise filter for highest stability and reliable operation.
This power supply differs from typical standard 5V USB power supplies in the market in that it can deliver a full 2.5A and still output a voltage well within the USB minimum voltage specifications. Standard 5V USB power supplies in the market have a high voltage drop when the full current is drawn from them which may cause the Raspberry Pi to reboot unexpectedly.
With this power supply, you can power the Raspberry Pi 3 at full load as well as up to 1.2A across the four USB ports. The power supply still has about 0.5A of output power to spare, so even at the maximum current supported by the Raspberry Pi 3, the power supply is not at its absolute maximum.
It is also ideal for use by anyone over-clocking the Raspberry Pi which causes higher power requirements that a lower power adapter may not be able to supply.
