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, 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.

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.

這是我們的金星GPS板的最新版本;體積最小，功能最強大，功能最全的GPS接收機我們進行。它是基於對Venus638FLPx，後繼者對Venus634LPx。為9600bps的違約率Venus638FLPx輸出標準的NMEA-0183或SKYTRAQ二進制句子（可調115200），與更新率高達20Hz的！該Venus638FLPx還允許有限的芯片上記錄（看看下面的固件），以及使用SPI閃存芯片外部日誌記錄（不包括）。

該板包括SMA連接器用於連接外置天線，為3.3V串行數據報頭，NAV（鎖定）指示，脈衝每秒輸出，並且支持外接閃光燈。我們也提供了焊料跳線方便地配置功耗，開機內存和備用電源。此板需要一個穩定的3.3V電源工作;在充滿電的電路板採用了90mA的，以減小的功率它需要高達60mA。

我們已經取得了很容易外部電池或超級電容器連接到電路板，電源被移除後，以支持非常快速的重新啟動。甚至有在板的下方為0.2F超級電容器片（不包括，但你可以在下面的相關項目中找到），這將讓董事會熱啟動的長達7小時的無動力！

注意：我們已經打破了對Venus638FLPx的第二個串行端口（RX1，TX1）和I2C接口（SDA，SCL）針腳。然而，這些端口不使用股票固件。 SKYTRAQ提供一個SDK允許定制固件的建立;與他們聯繫，了解詳情。
