is there a RTC with coin-cell battery on p4 crowpanel series?
Regarding the RTC — that's a fair point, and likely a decision made during the board's design/planning stage to leave it out. For the current version, you can add an external RTC module via the I2C header as a workaround. Thanks again for the feedback — we'll pass this along to our product team so it can be considered for future revisions.
