How to detect hardware type (ESP32 or ESP8266) in MicroPython?

How can I detect if my MicroPython script is running on ESP32 or ESP8266? I want to make it work on both platforms, but deep sleep requires different implementation depending on the hardware.

You can use uos.uname().sysname to detect the hardware platform.

Here is an example script:

import uos

print(uos.uname())

sysname = uos.uname().sysname
if sysname == 'esp32':
    print('detected ESP32')
elif sysname == 'esp8266':
    print('detected ESP8266')
else:
    print('something else')

Demo script output on ESP8266:

$ ampy run detect.py
(sysname='esp8266', nodename='esp8266', release='2.2.0-dev(9422289)', version='v1.11-8-g48dcbbe60 on 2019-05-29', machine='ESP module with ESP8266')
detected ESP8266

Demo script output on ESP32:

$ ampy run detect.py
(sysname='esp32', nodename='esp32', release='1.11.0', version='v1.11 on 2019-05-29', machine='ESP32 module with ESP32')
detected ESP32
