This is the latest version of the Venus GPS board; the smallest, most powerful, and most versatile GPS receiver.
It’s based on the new Venus638FLPx. 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
The Venus638FLPx also allows for limited on-chip logging (according to the firmware), as well as external logging using a SPI flash memory chip (not included).
This board includes a SMA connector to attach an external antenna, 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.
