This is the latest version of our Venus GPS board; the smallest, most
powerful, and most versatile GPS receiver we carry. It's based on the
Venus638FLPx, the successor to the Venus634LPx. The Venus638FLPx
outputs standard NMEA-0183 or SkyTraq Binary sentences at a default
rate of 9600bps (adjustable to 115200bps), with update rates up to
20Hz! The Venus638FLPx also allows for limited on-chip logging (check
out the firmware below), as well as external logging using a SPI flash
memory chip (not included).

This board includes a SMA connector to attach an external antenna
(required and not included, see the related items below), and headers
for 3.3V serial data, NAV (lock) indication, Pulse-Per-Second output,
and external Flash support. We've also provided solder jumpers to
easily configure the power consumption, boot memory, and backup
supply. This board requires a regulated 3.3V supply to operate; at
full power the board uses up to 90mA, at reduced power it requires up
to 60mA.

We've made it easy to connect an external battery or super capacitor
to the board, to support very fast restarts after power is removed.
There are even pads on the bottom of the board for the 0.2F supercap
(not included but you can find it in the related items below), which
will keep the board hot-startable for up to 7 hours without power!

Note: We've broken out the pins for the Venus638FLPx's second serial
port (RX1,TX1) and I2C interface (SDA,SCL). However, these ports are
not used by the stock firmware. SkyTraq offers an SDK allowing the
creation of customized firmware; contact them for details.
