That makes it an excellent choice for the Internet of Things IoT projects of all kinds. However, as a chip, the ESP is also hard to access and use. You also have to program it in low-level machine instructions that can be interpreted by the chip hardware. This level of integration is not a problem using the ESP as an embedded controller chip in mass-produced electronics. It is a huge burden for hobbyists, hackers, or students who want to experiment with it in their own IoT projects. But, what about Arduino? It also defines standard interfaces to interact with sensors or other boards. There is an Arduino reference design for the ESP chip as well. However, the flexibility of Arduino also means significant variations across different vendors. For example, most Arduino boards do not have WiFi capabilities, and some even have a serial data port instead of a USB port. The NodeMCU is available in various package styles. Common to all the designs is the base ESP core. Designs based on the architecture have maintained the standard pin layout. Some designs use the more common narrow 0. The most common models of the NodeMCU are the Amica based on the standard narrow pin-spacing and the LoLin which has the wider pin spacing and larger board. The official design is based on the CP chipset and offers the best compatibility. Other designs may use drivers including the FTDI chipset, but those designs are rare. We have experienced situations where both CP and CHG devices have not functioned or recognized as expected. The solution was as simple as uninstalling the old driver and installing the most recent version. The level converter allows true RS signals to be sent to the NodeMCU without worrying about the wide voltage swings. The switch toggles the data from either DB between Pin 2 or Pin 3 to the level converter. Finally, there is a jumper position at J1. Great to use for IoT projects, advanced or straightforward interfacing and as a prototyping platform. Features of the board include a mounting socket area to accept either wide 1. Alternately, power can be supplied to the IoT Experimenter board which has provisions for an integrated regulated power supply module. The board offers over 1, plated-through holes on the prototype surface, mounting for eight status indicator LEDs along with dropping resistors and a power indicator LED. The third rail can be used for external voltages such as a 5V rail. Each port is labeled to identify matching pins from the NodeMCU. The header area is located below the NodeMCU using standard pin headers allowing for versatility in interfacing for sockets or header pins. What is NodeMCU?
