Robotbanao 2 Channel 5V Relay Module NodeMCU ESP8266 Development Board + Jumper Wire 60 pc Electronic Components Electronic Hobby Kit

2 Channel Relay Module: This 5V 10A Dual Channel Opto Coupler Relay Module meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. The triggering of the 2 Road/Channel Relay Module is reliable, more stable. The double FR 4 circuit board design, high end SMT process. It has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. NodeMCU WiFi Development Board: NodeMCU ESP8266 LUA Amica WiFi IOT Development Board CP2102 has powerful onboard 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 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. This board has ESP8266 which 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. 60 Pcs Jumper wires: This is the combo of 20CM Wire Color Jumper Cable, 2.54mm 1P 1P M M, M F, F F 20 PCS of wire in each strip of cable. It is very Flexible and easily detachable to no. of wires to your requirement. It is compatible with 2.54 mm mil spacing pin headers. This 20CM Dupont Wire Color Jumper Cable is an electrical wire or group of them in a cable with a connector or pins at each end, which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components, without soldering. Package includes: 1 x 2 Channel Relay Module 1 x NodeMCUWifi Development Board 1 x 20CM Wire Color Jumper Cable, F F, M M, M F(60PCS)
