Yikes, just the other day I suggested that higher voltages should be OK because they have a switching regulator.
Due is similar to uno regarding VIN node. We should keep the recommended input voltage between 7-12V. Supplying more than that, let's say 13V, will affect the IC1B (LMV358IDGKR) comparator input (CMP - +3V3). When you supply a 13V, the VIN node will drop down to 12V due to D1. The 12V is then divided into half by RN4C and RN4D to 6V, which is more than the LMV358 maximum input rating (5.5V). So, if we supply more than 12V, the LMV358 will pay.
