The VBat conductor between the Sparkfun TOL 10617 battery positive pin and the BAT/BAT 2 inputs to the MAX8903A charge management IC U2 (pins 21 & 20) is shorted to ground on the PCB by a flood-filled polygon zone. This is on the top copper layer. The design rule checker does not mark the intersection of the polygon with the track as a problem.

The net result is that U2 (MAX8903A) fails to regulate properly and the board fails to operate (dead short/no voltage). With the battery pack connected, the pack delivers peak current (3x 5A) to ground, with the associated fire risk due to battery failure.

The work-around is a careful scalpel cut along the edge of the track to separate the polygon from ground.

During compilation of the Atmoscan 1.4 sketch the following error is produced :

Any idea how to solve this ?

Thanks and kind regards,
