(Video) For the ESP32 Pico QT Py, we will be including a CP2102N (covered a few weeks ago!) to do USB to serial conversion. We also need a dual NPN transistor to do the funky reset/boot toggle required to reset the ESP32 into bootloading mode. On our Feathers, we used two SOT-23’s but we have so little space, we’d like to find something the same size as our BSS138 duals we use on STEMMA QT sensor boards!
