What is it?

This is a all in one board I use for NodeMCU's to connect BME280 for temp humidity and pressure, SSD1306 screen, DS18B20 temp sensor if all I want is temp, LDR, HX711, and More. Every pin on the NodeMCU is broken out to help with connecting inputs and outputs. If you don't need the LDR then leave off the 10K resistor and connect a 2.5 mil pitch JST connector to SENSOR_1 to have a clean connection for 3.3v, GND, A0, and D7 pins.

Why did you make it?

I had a bunch of purpose built boards for temperature measurement, load cells for scaling, boards for contact sensors, water leak sensors, etc... I made this all in one board to help me standardize my home sensors to this one board and then I run ESPhome on the NodeMCU to interface with Home Assistant running at the house.

What makes it special?

I call it NodeMCU multi-controller because I use it for for all my NodeMCU projects. Both sizes of esp8266 NodeMCUs can be used with this board.(Large ESP8266 and Small ESP8266)
