NodeMCU ESP-12E ESP8266 WiFi LUA CP2102 V2 and motor shield L293D DIY robot USA

Motor shield for ESP-12E Introduction: This is the first motor shield for ESP8266 based on ESP-12E.  Features: Name: ESP-12E motor shield; using ESP-12 DEV KIT development shield module; extend the output ports for ESP-12 DEVKIT: SPI, UART, GPIO, AI and 3.3V power interface; extend 2-ways motor, then can directly drive 2-ways motor; design a power switch; driven chip: L293D; voltage for motor: 4.5V-36V; voltage for ESP control board: 4.5V-9V;   The ESP8266 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 runtime. Its high degree
