I need to save space on my breadboard to keep things neat. As such, I have implementations where I attach a 4 pin device across 4 Teensy pins...and set two of the pins as inputs on the Teensy and connect them to GND and VCC. This leaves two pins for a serial connection and powers the device.
Are there any drawbacks or limitations to this kind of connection? I just want to make sure this can't catch up with me later.
