ESP8266 ESP-12E USB WiFi Module

OVERVIEW:

The LoLin V3 NodeMcu Lua WIFI Development Board is a highly integrated chip designed for the needs of a new connected world. 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. It 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 run time. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including the front-end module, is designed to occupy minimal PCB area.

The LoLin V3 NodeMcu Lua WIFI Development Board combines an 80Mhz 32-bit processor with 802.11 a, b, g and n support in both station and router modes at a fantastic price point, enabling a pervasive, low-cost Internet of Things. It comes in various different flavours and while Hobbytronics Pakistan hasn’t tried them all we have tried a lot. We decided to pick the latest version of the NODEMCU, the V3. The primary difference between the V2 and the V3 is the use of the ESP-12E module, which exposes GPIO 9 and 10 – another two GPIO pins come in very handy.

Features:

• ESP8266 microcontroller NodeMCU Lua WIFI with CP2102 USB
• Expand two-way motor-driven, two-way direct-drive motor.
• Motor power supply (VM): 4.5V 36V; Control power (VIN): 4.5V 9V (10VMAX); can be powered separately.
• The module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V 9V) while completing motor drive and control.
• Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power to the motor and the control board.
