Today Jeroen and I found that the footprint of the crystal oscillator for the RF module is upside-down, the crystal was removed because it was causing a short circuit between pins 25 and 26 of the MCU.
As we are not using batteries at the moment to test our circuit, we are relying on the USB interface of the programmer; a bridge was soldered in the footprint of the battery charger as we don't have such a component to link the input voltage coming from the USB connector to the PCB of our sensor (pins 3 and 4).

Welcome
This blog will serve both to log our improvements on the project and to keep trace of the solutions we came up.
Every single event and conclusion should be uploaded for further review.
