What this episode covers

For the SCORPIO Feather, we need to buffer 8 outputs for NeoPixels from a 3V signal to a 5V signal. The '245 is the transceiver we have traditionally used - but we need a very smol chip, that can also handle if the logic level is 3V and the power supply maybe gets towards 5.5V, thus getting dangerously close to 1/2 VCC. We'll show why the T is important!
