The new revision of the Triggy Node has been built and verified to be functional today. Reminder: a new revision was required because the magnetometer MEMS MAG3110 was no longer fabricated. So I decided to use the LIS3MDL which works perfectly. It is also the lowest power consuming among the 3 magnetometers I experienced.
Schematic has been added in the git repo.
As seen on the picture below, the design is very close to the 0.3 version, only the part around the magnetometer has changed.
