Looking for a GPS board? This is the latest version of Sparkfun's Venus GPS board; the smallest, most powerful, and most versatile GPS receiver. 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.

Q: this module is avaiable at $49 in sparkfun...and its price is 6375!!!.......thats way too high.......this is one of the problem of techshop...... Questioned by mamundip, 16-Feb-2013

Do you really know how things work? Do you know the dollar rate? How much the freight charge? The custom's fee? I guess you don't. Unless you can give a better suggestion, please refrain from this type of comment. I am bit of a harsh to you, because we are working hard to provide things in lower price, while you point out that as our "problem". Thank you for understanding.
