The NodeMCU (Node MicroController Unit) is an open-source software and hardware development environment built around an inexpensive System-on-a-Chip (SoC) called the ESP8266. The ESP8266, designed and manufactured by Espressif Systems, contains the crucial elements of a computer: CPU, RAM, networking (WiFi), and even a modern operating system and SDK. That makes it an excellent choice for the Internet of Things (IoT) projects of all kinds.
The NodeMCU is available in various package styles. Common to all the designs is the base ESP8266 core. Models based on the architecture have maintained the standard 30-pin layout. Some designs use the more common narrow (0.9″) footprint, while others use a wider (1.1″) footprint.
The most common and compatible model is the NodeMCU from Amica. This carrier board incorporates the genuine Amico NodeMCU ensuring the most compatibility.
Included on the carrier board are a pair of DB-09 connectors and MAX232 style RS-232 level converter providing data to the NodeMCU.

The NodeMCU Carrier Board can also be used in the NodeMCU IoT Experimenter. The IoT Experimenter is an advanced prototyping platform with a large prototype area along with a heavy-duty power supply facility. The full kit of the NodeMCU IoT Experimenter includes all parts, including the NodeMCU Carrier Board. Alternately, the NodeMCU IoT Experimenter can be purchased as just a bare board and you supply all components including your choice of NodeMCU modules.
The original design of the Carrier Board was for a WiFi application and the serial ports allowed for RS-232 data to be provided over the serial connectors, through a MAX232 compatible level converter to the NodeMCU. The level converter allows true RS-232 signals to be sent to the NodeMCU without worrying about the wide voltage swings.
