I have put my RS232 adapter board for GPS modules up on OSHPARK's shared projects page.
https://oshpark.com/shared_projects/YPvKgMYa It has connectors and holes for the Adafruit Ultimate GPS, Trimble Resolution T timing receivers, and generic (Vcc/Gnd/Tx/Rx) devices (like the popular Ublox NEO-6M based Crius CN06). The 1PPS signal is routed to the RS-232 connector via the MAX232A, polarity is selectable. There is a small prototyping area including an 8-pin DIP for a ATTINY CPU, etc. GPS/MAX232A power can come from an on-board regulator or the DC IN jack. Note: use a MAX232A chip with 0.47uF caps, not the CP3232 marked on the silkscreen... CP3232's are way too picky about their caps. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
