1.1.1 WiPy
Deep Sleep current issue
The LoPy, SiPy, and WiPy 2.0 experience an issue where the modules maintain a high
current consumption in deep sleep mode. This issue has been resolved in all newer
products. The cause for this issue is the DC to DC switch mode converter remains in a high
performance mode even when the device is in deep sleep. The flash memory chip also does
not power down. A more detailed explanation can be found here.
