Hello,
It is possible to use a MOD-RS232 and a MOD-RTC on the same UEXT1 connector please?
Kevin
If you look at the schematic you will see this is possible if R8 and R9 are not fitted on the RTC as the RTC uses the UART TX and RX pins for CLKOUT and #INT.
The schematic shows these as NA (not assembled) so if your RTC board does not have these fitted, it should work.
Thank you Dave, I wasn't aware of what NA meant! And having looked at the PCB I can now see that those components are indeed not there :)
Great stuff - thanks!
Kevin
