After installing sketch timer wake up,current in deep sleep 11mA (not µA).
Power supply 5V at Vin ,also tried 3,3V at 3V3 input.
Stay the same 11mA instead of µA , USB disconnected
Yes, that’s true.We’re currently working on a project with ESP32 that requires deep sleep and we’re also getting around 9 to 11mA.
The ESP32 datasheet says it consumes around uA for the bare chip. But, the development board we’re using has a lot of on-board components that consume power even in deep sleep. You can desolder some on-board components to save power. For example, removing the on-board LED will save a few amps, or desoldering the voltage regulator GND pin (and don’t use the USB).
But we haven’t achieve the uA values. I think that we would need to use the bare chip for that.
