This article will describe how to setup the SparkFun DataLogger IoT - 9DoF
initially described here and here in these two previous articles with a SPARKFUN GNSS RECEIVER BREAKOUT
This Sparkfun MAX-M10S GNSS receiver board can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations of satellites. The board is also equipped with an on-board rechargeable battery that provides backup power to the module’s Real Time Clock (RTC). This reduces the time-to-first fix from a cold start (~24s) to a hot start (~1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. This increases precision and decreases lock time in battery operated devices without compromising GNSS performance. This Sparkfun u-blox GNSS receiver supports I2C which makes it perfect for Qwiic compatibility. Here is summary of the specifications:

This demo will show how to connect the Sparkfun MAX-M10S GNSS receiver board via the Qwiic I2C interface using one of these useful Qwiic cables,
available from DigiKey. Also using the following active muliti-band GNSS antenna (L1/L5/E5a/B2a/NavIC) RHCP single-feed stacked-patch antenna element, with a built-in LNA with SAW pre-filtering, and a 3-meter antenna cable with an SMA connector,
available from DigiKey. This antenna is connected via the RF SMA connector to the SPARKFUN GNSS RECEIVER BREAKOUT. In order to connect the Sparkfun MAX-M10S GNSS receiver board with the SparkFun DataLogger IoT - 9DoF, connect both using one of these useful Qwiic cables.
Here is a picture of the complete setup of the demo showing the I2C Qwiic cable, the antenna connection and the USB cable to the host,
In order to setup the SparkFun DataLogger IoT - 9DoF open a minicom terminal as follows,
digikey_coffee_cup # minicom -D /dev/ttyUSB0 -b 115200
After pressing the reset button in the SparkFun DataLogger IoT - 9DoF board select the following options illustrated below to configure the GNSS - u-blox GNSS receiver

to enable all parameters from the GNSS - u-blox GNSS receiver receiver to be read by the SparkFun DataLogger IoT - 9DoF board. These GNSS receiver values are stored in the SD card and also if configured properly using the previous article setup description IoT HTTP WiFi server, these can be sent via the internet to another cellphone or computer using JavaScript Object Notation (JSON) format as needed.
After the x is pressed in the setup
Since all parameters were enabled, many of them are shown in the minicom terminal, like the classical lattitude, longitude, etc.. All of these parameters can be customized, that is if some are not needed repeat the previous configuration and select the only ones needed for the application.
This article gives an overview of how easy is to setup the SparkFun DataLogger IoT - 9DoF with the Sparkfun MAX-M10S GNSS receiver board that can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations of satellites using the active muliti-band GNSS antenna (L1/L5/E5a/B2a/NavIC) RHCP single-feed stacked-patch active antenna element for applications where location information is needed. All of these items are available at DigiKey. Have a nice day!
