Deep Sleep amps too high?

Without deep sleep it pulls 37mA. When I turn on deep sleep I get 10mA. Although that's better I was expecting < 50uA. Is that because it's running MicroPython? Do I need to do something else to get it much lower? Thanks.

Do you use the bare ESP32 or a board with it? The USB/UART bridge chips are not put to deep sleep and can consume up to 20mA.

I didn't realize the boards were so different. I was using an ESP32 development board that was relatively large. I then went to the ESP8266 Wemos D1 Mini. It's still a development board but now I'm getting 100µA in Deep Sleep. Thanks for the info. Do you know of a board, any ESP, that gets even less?

TinyPico with 10-20 uA in deepsleep.
