Review on 🛰️ High Sensitivity GPS Module NEO-6M for Navigation Satellite Positioning - Compatible with STM32 Arduino UNO R3 & 51 Microcontroller, Drone Receiver with IPEX Antenna by Tory Richardson

My app is for timing and certainly not for flight control. This module was fascinating because of its low price compared to other modules. Serial port/terminal. • Operates at 5V and I have verified on the oscilloscope (and in use) that the TTL levels are both TXD and PPS output. it turns out that positive transitions mark *next* sentences received and seconds = 00. Note that PPS are only shown if there is actually a fix (e.g. $GPRMC status term = 'A'). The small red LED on the breakout board appears to be wired as an inverted PPS, so will be solid red until corrected and then flash along with the PPS. Healthy. • I have confirmed that two independent patch engines run PPS exactly in tandem, as expected. • Output sets (at 1s intervals 9600 baud): ($GP)RMC, VTG, GGA, GSA, GSV and GLL. I only needed RMC and GGA • The position output was accurate, at least when the static was on my desk. There was no need to evaluate it in motion. • Suggestions seem to work well with regular GPS analysis libraries or when using your own. • Breakthrough module looks like a small rechargeable button cell spot welded to its holder, hot start capability • Supplied short pigtail antenna with U.FL connector works well. The same applies to the more solid GPS antenna with U.FL. Note that U.FL connectors are not designed for repeated mating cycles. this. they are fragile! Use a magnifying glass when connecting. What concerns me: • Revain's supplier description states that it uses "Original UBLOX (sic) 7th Gen Chip". Obviously the "GT-U7" module on this breakout board does not claim to be a u-blox product. Is an "original" Ublox chip used internally? Reading the ublox website on how to identify a fake, you might think that it's actually some sort of clone of u-blox Neo 6 or 7, actually configured via u-center, although u-center has no problem parsing its output. If you're expecting something real Ublox, do your research. • It is questionable how robust the 5V RXD, the only entry into this breakout, can be. Since I don't plan on sending it any configuration, I leave it disabled and use the module in its default mode. • A schematic representation of this riser would be very helpful, especially to answer the previous question. Can't find it for him. Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh It's easy enough to reengineer if you have the motivation. So can I trust this product in my 1/8 scale RC A380 standalone jet model? Probably not. But it works fine for my timing app, so I'm not deducting stars as I'm being realistic with its parentage. ---
