 On the GPS-E1 breakout board there is a 2x36 0.1" pin header, one strip is ground, the other is various connections to the GPS-MS1. There are quite a few jumpers on the board, as well as a socketed CR2477 lithium battery (still holding a good charge!), a small rectifier feeds a Traco DC-DC converter taking 9-18v to 5v, with another 3.3v regulator on the bottom of the board, making this thing very easy to power. There's a reset button and a firmware upload initiate button, as well as quite a few jumpers. One jumper (three pin J2) has an SPDT switch connected to it. I have not yet mapped out any of these jumpers, but it should be easy to do so given how simple the board is.

+By default it sends the SiRF binary protocol, but it can be configured for NMEA. `gpsd` supports the SiRF binary protocol out of the box, so I have as of yet not reconfigured it. Eventually I plan to feeds it's PPS into my tinyGTC vs an LEA-M8T to see how the two compare.
