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.
