The NodeMCU board is essentially a breakout/development board for the ESP12E module by AI-thinker.

To resolve some of the issues associated with these modules, several breakout and development boards based on these modules were made such as the Wemos D1 (which worked like the Arduino Uno) and Wemos Mini boards, but none of them quite achieved the same level of popularity as the NodeMCU. Several other versions of the modules were made but they all had similar constraints. The chips had little (written in Chinese) or no documentation and this made them even more difficult to use. Users, however, quickly discovered several constraints from the power requirements to the breadboard unfriendliness of the chip. So when the first version of the ESP8266 module (ESP-01) came to market, it was an absolute delight as the low price and quality drove the popularity of the chip. All those modules were either too expensive or quite complex to use. The Arduino came at a time when the IoT revolution was starting out and it gave makers the opportunity to be part of that revolution by building simple connected devices, combining the Arduino and several different kinds of WiFi and Ethernet modules/shields. Move it to your Multisim™ working folder and then follow the instructions for merging the library. usr file extension and then correlated the file creation time. Find it by searching in C: drive for the.

If the problem still persists: the conversion from one version of Multisim™ to another appears to generate a new file and places it deep in the windows file structure.

You can find this in Tools>Database>Convert database.

Keep in mind that if the Multisim™ version does not match the template version, you will have to use the Convert database option which works the same way as the Merge database.When Multisim™ asks you for the database file, you should select r.Check if you are able to access to your User Database and if you have any components in it by opening Place Component (right-click or ), then in the Database dropbox select User Database.If the problem persists, since you already have the correct version, check if you have access to the Database.Be sure to have Circuit Design Suite (Multisim™ and Ultiboard) version 13.0 (or later).SolutionThere are several solutions for this error:
