NEW PRODUCT – Basic GPS module – PMB-648. We picked up a few of these lower-cost GPS modules specifically for those that want to use them for time-keeping purposes. They function perfectly fine as a GPS, but they are not as accurate or low-power as the EM-406 modules we carry for location applications. For that reason, we don’t suggest them for precise, battery-powered location logging.
However! They will still get you precision time, can get a fix while near a window, and have a built in RTC. Great for hacking your Ice Tube Clock (as seen in our tutorial) or MONOCHRON, or other DIY clocks.
The PMB-648 GPS features 20 parallel satellite-tracking channels for fast acquisition of NMEA0183 v2.2 data for robotics navigation, telemetry, or experimentation. There is a built-in patch antenna; rechargeable battery for memory and RTC backup; cable for power, TTL and RS-232 connections.
