I have a project that needs accurate timer so I would like an accurate RTC with an interrupt such as DS3231 to fit in the enclosure. Needs 3v SDA SCL and IO for the square wave
Other requests:
GPS module for position and timing. Needs serial, power and IO for pps signal.
Small plugs to cover up unused ports.
Could the battery chassis have an alternative deeper back to accommodate a 40 pin breakout and user extension boards?
Thanks.
