🌐 MakerFocus Waterproof GPS Antenna with SMA Connector for Vehicle Tracking and Navigation Review

Works great. Mine gave a fairly quick first fix out of the box (expected around 10 minutes) and after that it warmed up in under a minute on average. I tracked up to 9 satellites indoors under a tiled roof with GPS quality 4 (RTK) and DOP values below 2.0. Please note that this is a 3.3V device. The VCC pin is set to 3.3V and can accept 5V, but all data pins are 3.3V. You can connect the Tx and PPS pins directly to the 5V TTL inputs (e.g .Arduino) ) and it will work fine - absolutely safe. You…

This little unit is great value for money. It appears to be using a real U-Blox chip under a metal can and white label. Most features of the U-Center software appear to work well. I connected mine to a Raspberry Pi 2 to create an NTP time server. The PPS connection offers an accuracy of tens of nanoseconds. To do this, the Raspberry Pi must be configured to receive a PPS signal on one of the GPIO pins. I used the "GPSD" and "NTPD" packages, which work fine with the device. Do not forget…
