A voltage regulator / RS232 breakout board. Has mounting holes for Adafruit, CN06 (Ublox Neo 6M) and Trimble Resolution-T receivers. Others receivers can be wired to the board.
Silkscreen says CP3232 RS-232 converter chip. These are too picky about their caps. Use a MAX232A with all 0.47 uF caps (MAX232A’s seem to work just fine on 3.3V).
Regulator is any AM1117 compatible fixed regulator.
PWR RAW/REG jumper selects whether the GPS/MAX232A receivers power from the regulator or the input jack.
RS232 PWR jumper connects pin 9 of the RS232 connector to the DC input jack.
PPS polarity jumper selects polarity of the PPS pulse to the RS232 connector.
There is an 8-pin DIP pattern for an ATTINY85, etc processor.
Resolution-T antenna power is wired to Vcc, but there is a place to cut the etch marked on the board along with a hole for providing an alternate source of antenna power.
