IPC3 Change in RTC battery type

Post by tamir »

IPC3 is changed from soldered rechargeable battery to non-rechargeable battery on wires connected by W2B connector to the SBC.
The goal of this engineering change is to improve reliability of CMOS retention and RTC time keeping.
Non-rechargeable batteries are found to be more reliable than rechargeable ones, last in IPC3 for over 5 years under normal usage scenarios and are easy to replace.

The change applies to SBC serials staring from: 171024-xxxx
