Hi,
I am new to MCUs and in the process of designing a home sensor for temp/humidity/water detection. To get started, I decided to tackle the first problem: getting a steady supply of power to the breadboard. It all works in real life but wanted to also start designing the schematic for it as it will be needed once I get to PCB design for the whole sensor unit.
The design is based on reading about SparkFun's power supply kit as well as a few other tutorials and youtube videos. Eventually, the system will be powered by a 9v battery (instead of converted DC from the wall) and output 3.3V. This schematic will be part of a larger schematic which would include the sensors, MCU, etc.
Would appreciate if anyone could provide any feedback on the schematic. I understand its pretty simple, but are there better design practices that I could follow? Should I have multiple GND or have those be connected to the same? Should I extend out a GND connecter? Good reading on the topic?
Thanks,
Shawn
