| 21 | +u-blox makes some incredible GNSS receivers covering everything from low-cost, highly configurable modules such as the SAM-M8Q all the way up to the surveyor grade ZED-F9P with precision of the diameter of a dime. This library focuses on configuration and control of u-blox devices over I2C (called DDC by u-blox) and Serial. The UBX protocol is supported over both I2C and serial, and is a much easier and lighterweight interface to a GNSS module. Stop parsing NMEA data! And simply ask for the datums you need. |
| 22 | + |
| 23 | +This library can be installed via the Arduino Library manager. Search for **SparkFun u-blox GNSS**. |
| 24 | + |
| 25 | +Although not an integrated part of the library, you will find an example of how to communicate with the older series 6 and 7 modules in the [examples folder](./examples/Series_6_7). |
| 26 | + |
| 27 | +Max (400kHz) I2C Support |
| 28 | +------------------- |
| 29 | + |
| 30 | +To achieve 400kHz I2C speed please be sure to remove all pull-ups on the I2C bus. Most, if not all, u-blox modules include pull ups on the I2C lines (sometimes called DDC in their manuals). Cut all I2C pull up jumpers and/or remove them from peripheral boards. Otherwise, various data glitches can occur. See issues [38](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/38) and [40](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/40) for more information. If possible, run the I2C bus at 100kHz. |
