User LEDs
: There are 2 LEDs (blue color) available for use with own TMCL scripts to react on user
interaction or indicate certain conditions. The corresponding IOs are described in the firmware
manuals.

Charge Level / Status LEDs
: There are 3 LEDs of different color to indicate the charger state when a
5V USB-C charger is connected and the Li-Ion cell’s charge level when no USB-C is connected. When
charging the green LED is blinking. When not charging the green LEDs are permanently on and are
roughly indicating the charge level: green = good, yellow = middle, red = need to charge.

The battery holder is assembled on the bottom side. A 18650 type/size battery fits into.
A 2A fuse is used to limit the maximum current draw from the battery.
Note
Please check polarity of the battery before insertion! The proper polarity is
