We released version 1.4 last friday, fixing issues with auxiliary power in sleep mode. Unfortunately I introduced a bug in the drive mode of the J_TIP pin.
We have just released a new version 1.4.2, that fixes this bug!
The bug caused the power consumption to be much higher than normal, when mono was running. Therefore we strongly encourage everyone who downloaded version 1.4.1 (this weekend), to upgrade to version 1.4.2:Windows macOS Linux (Debian & derivatives)
Sorry about the inconvenience.
