I have ask here http://www.microchip.com/forums/m951726.aspx#951878 but without response.
My cpu and all the other electronics work fine. I have try to coated the pcb with an epoxy resin but without solve the problem. The power supply and the battery are stable at low temperature
Someone else have the same problem with this module?
