A PCB to take your breadboard project to the next level. There are 3 I2C connections from D1 and D2 as well as 3.3v and Gnd - a common (but not universal) connection from sensors like the BME280 Temperature and Humidity sensor, OLED display, and the MPU6050 Accelerometer/Gyrometer
2x 3.5mm mini-pin jacks wired to D6 and D7 with a resistor between them for 1-wire (in my case 2 DS18B20 waterproof temperature sensors)
Another 3.5mm mini-pin jack wired to A0, 3.3v, and D3 - which I generally set to LOW as GND. I use this as a makeshift Water sensor probe with a standard male to male mini-pin cable which works remarkably well.
And Button wired to D5 - I use it to reset WIFI
There are mounting holes for standoffs on 3 corners
Use one or all of the breakouts - they work independently
I have about 20 sensors around the house; breadboards weren't cutting it anymore.
The cool blueish color and gold pads ;-)
