Show Notes
We're back from visiting family, but we do have some goodies on our desk to show off. One is our ESP32-S2 TFT Feather did get wrapped, we wanted to make sure our low power mode is right - we made a mistake with the pullups on the earlier version. We also have a new Feather we finished designing with the code name SCORPIO!
The Great Search - 74AHCT245 Small 3V to 5V logic level shifter

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!
