1-6 Lassen-SK8 Embedded GPS Module
Starter Kit
The receiver module (see Figure 1-2) consists of a single 3.25" x 1.25" x 0.40" module. A
standard SMB RF connector (J1) supports the GPS antenna connection. The center
conductor supplies +5 VDC for the Low Noise Amplifier of the active antenna. An 8-pin,
0.1 inch header (J4) supports the serial interface (CMOS TTL level), the pulse-per-second
(PPS) signal (CMOS TTL level), and the input power (+5 VDC). This module connects to
the motherboard via the 8-pin header and is secured by two standoffs. An RF-interface
cable connects the antenna port to an SMB connector on the enclosure panel.
