NodeMcu ESP8266 V3 with CP2102
NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the development kits. The firmware uses the Lua scripting language.

NPN Transistor variable range
In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN (Negative-Positive-Negative) type and a PNP (<b”>Positive-Negative-Positive) type.</b”>
The most commonly used transistor configuration is the NPN Transistor. We also learnt that the junctions of the bipolar transistor can be biased in one of three different ways – Common Base, Common Emitter and Common Collector.

NRF24L01 with antenna V5.0 + PA + LNA wireless Module 1000 meters Long Range
IoT & Wireless, Modules & SensorsNRF24L01 with antenna V5.0 + PA + LNA wireless Module 1000 meters Long Range
The NRF24L01 module is the latest in RF modules. This module uses the 2.4GHz transceiver from Nordic Semiconductor, the NRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature – very nice!
This board features a reverse polarized SMA connector for maximum RF range. And there is PA and LNA circuit on board, with the external antenna it can reach long distance than the one without these parts.
This module comes with the 2.4G antenna (2DB), with 250Kbps transmission rate on open air it can reach the 800-1K meters communication distance.

Display Module
OLED 0.96″ Display Module I2C Display 128X64 OLED
Three different colour types available Please make specify before place order
This is a 0.96 inch OLED display module. The display module can be interfaced with any microcontroller using IIC protocols. It is having a resolution of 128×64. The package includes display board,display, 4 pin male header presoldered to board.
OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.
OLEDs basic structure consists of organic materials positioned between the cathode and the anode, which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film, which includes the Hole Transporting Layer (HTL), Emission Layer (EML) and the Electron Transporting Layer (ETL). By applying the appropriate electric voltage, holes and electrons are injected into the EML from the anode and the cathode, respectively. The holes and electrons combine inside the EML to form excitons, after which electro luminescence occurs. The transfer material, emission layer material and choice of electrode are the key factors that determine the quality of OLED components.
