3pcs Wireless Transceiver Module, RF Transceiver Module, 2.4G 1100m NRF24L01+PA+LNA SMA Antenna for Raspberry Pi Arduino KY67

2pcs ESP8266 Serial Wireless Module CH340 NodeMcu V3 Lua WIFI Internet of Things New Version Development Board EK1677 Arduino Compatible Description: A great set of tools to develop ESP8266. NodeMCU is built based on the mature ESP8266 technology to take advantage the abundant resources available on the web. NodeMCU has ESP-12 based serial WiFi integrated on board to provide GPIO, PWM, ADC, I2C and 1-WIRE resources at your finger tips, built-in USB-TTL serial with super reliable industrial strength CH340 for superior stability on all supported platforms. 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. 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 run-time. 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. Package Including 2 * NodeMcu Lua ESP-12E WIFI Development Board
