Package contents
1x NodeMCU Base with DC input
Why choose this product?
It provides a clear pin layout of the NodeMCU development board into accessible connector rows.
It allows power supply from an external DC source without the need for separate power connections outside the base.
Mechanically attaching the module to the sockets simplifies board replacement during development and testing.
The compact design is suitable for workbenches, development fixtures and integration into prototypes.
Installation and operating instructions
Only install the NodeMCU module when the power is disconnected.
Before connecting an external power source, verify the polarity and input voltage range specified for this base.
When inserting the module, ensure the correct orientation of the pins relative to the sockets and the description on the board.
Connect the connected peripherals according to the markings of the individual pins on the PCB.
Safety notice
Incorrect power connection can cause damage to the base, the installed module and connected devices.
Do not short-circuit the power pins or data pins.
Operate the board in a non-conductive and dry environment.
When developing and integrating into a device, it is necessary to observe the correct electrical connection and load of individual pins according to the NodeMCU module used.
The product is intended for electronic development and prototyping; installation into the final device should be performed by a person with electronics knowledge.
