Review on 📡 High-Precision GPS Receiver Module NEO-M8N BDS Compass for Drone Microcontroller, APM PIX PX4, I2C Compatible with MWC - Integrated APM Flight Control Pixhawk Navigation Module by Adam Cooper

Contacted seller support and sent replacement and additional fee. The replacement works - and my other one works with the Arduino hardware. The product works as expected. I am satisfied with this purchase and the support. This GPS board uses a U.FL/I-PEX connector for the included antenna - and these connectors are small and not very easy to connect. There are websites how to do that. I've found that the time it takes to line up perfectly and then press down very straight and firmly helps. Achievement is usually obtained when a good CLICK occurs. I pre-test them by connecting them to a PC via USB and then running PuTTY (9600 baud) to see the result. The $GPGxxx strings are automatically generated and their format is described by many different websites. It looks like 8-9 satellites need to be found to show valid data. Old (obsolete) review: I bought 2 of these to use with Arduino (microprocessors) for an embedded application. One works and the other doesn't. No satellites are tracked unsuccessfully. The price is nice, but - only if the product works.
