So, that works the same as my previous larger ESP32 board, it’s surprising how small these WiFi/BT boards are getting.

Just need to work out how to get a BT wake-up from deep sleep communication between the ESP32 and my iPhone.

To conserve battery power I want to keep the quiescent current of the ESP32 as low as possible when it’s not required but be able to switch it on from Dabble.
