Usually one core takes care of the app, the other of some stack components... even though both BLE and WiFi are off - to be assumed on the other core - I think there is still something on and going on on that core when Espruino is going. Putting the input pins on input_pullup or input_pulldown - what ever is available - could make a difference. But thank you fort the measuring again and confirming.
