SparkFun GPS Breakout
NEO-M9N, SMA (Qwiic)
-
The SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options including SMA. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions increasing, precision and decreases lock time; and thanks to the onboard rechargeable battery, you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

While the I²C interface seems simple on the surface, this straightforward architecture is not immune to intermittent glitches, device misbehaviors, and protocol violations. Likewise, tracking down these errors can be tedious business if the right tool is not utilized.The CAS-1000-I2C/E bus analyzer is an exceptional tool for pinpointing I2c irregularities. The ability to spot complex problems and identify invisible obstacles make it the preferred I²C development solution. Advanced logging, debugging, emulation, and verification capabilities offer power and versatility, yet the Windows-based user interface makes the most complex features simple to use.The CAS-1000-I2C/E succeeds where simple monitoring and interactive I/O tools fall short—a complete solution to monitoring, emulating, stressing, and characterizing I²C and SMBus interfaces.
