The hardware part of Minerkeeper has received an update and we are happy about it!

Following the migration from the LCD display to the Android app, some components such as terminal blocks for connecting the display and rotary encoder were eliminated, making the layout cleaner.
The possibility of propagating the alarm signal to further external devices via the NO contact on the board is introduced. This way you can send the alarm signal to fire control units, telephone dialers or external sirens.

In the two photos below you can see the comparison between version 1.0 (left photo, purple board) and version 1.1 (right photo, yellow board)

There is now a red led to show there is an active alarm and the relevant button for resetting the alarms.

Finally, the colors of the card are now coordinated with the colors of the logo (black/yellow). Aesthetics are also important!
