Buses and GPIO pinout🔗

I2C1 Bus🔗

RTC RV-3028-C7🔗

Address 0x52

Note

The schematic does include the RTC RV-3028 but due to a lack of software support; it was removed in production at Fairscope. Some PlanktoScope hat units may have it but that is currently unsupported. The PlanktoScope v3 will have complete RTC support.
