NodeMcu v3 Basic Base Board

NodeMcu v3 Basic Base Board

This baseboard is specifically designed to simplify the prototyping process for the NodeMCU V3 (Lolin) board. It breaks out the GPIO pins, as well as power lines like Vin, VUSB, 5V, 3.3V, and GND, into easily accessible header pins. This makes it ideal for jumper wire connections during prototyping. Additionally, the board includes an onboard voltage regulator and DC barrel jack input for flexible power options.

Package Includes:
