2 pcs ESP8266 Module: 1 pcs CCL & 1 pcs Metal
ESP8266 is a highly integrated chip designed for the needs of a new connected world. NodeMCU, is an open source networking platform. It uses Lua scripting language programming
It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application.
Specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.
Color:black
CCL ESP8266 Module:
This baseboard is fitted with an onboard switching DC-DC buck (wide input range) and a standard 5.5 x 2.1 mm DC socket, mounting holes and numerous headers are available to esase NodeMCU V3 module usage
Allows developers to deal with the underlying hardware in a manner similar to for Arduino
Applies to the basic testing of the DIY breadboard for LoLin V3 NodeMcu Lua WIFI
Material:CCL
Size:6*6cm
Metal ESP8266 Module:
Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
Great way to connect your Arduino or other microcontroller projects to a WiFi network.
Prototype your IoT (Internet of Things) products within a few Lua script lines.
Power your developement in the fastest way combination with NodeMCU Firmware.
