It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, nine degrees of freedom (9DOF) on a single board. The LSM9DS1 from STMicroelectronics is equipped with a digital interface, but even that is flexible. This IMU-In-A-Chip is so cool we put it on the quarter-sized breakout board you are currently viewing.<\/p>\n<p>The LSM9DS1 is one of only a handful of IC\u2019s that can measure three key properties of movement, angular velocity, acceleration, and heading, in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object\u2019s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x\/y\/z, angular rotation in x\/y\/z, and magnetic force in x\/y\/z. The LSM9DS1 Breakout has labels indicating the accelerometer and gyroscope axis orientations, which share a right-hand rule relationship with each other.<\/p>\n<p><strong>DL2309Mk05<\/strong><\/p>\n<p>1 x SparkFun Thing Plus &#8211; ESP32 WROOM<br \/>\n1 x DS3231 Precision RTC FeatherWing<br \/>\n1 x GPS Receiver &#8211; GP-20U7 (56 Channel)<br \/>\n1 x SparkFun 9DoF IMU Breakout &#8211; LSM9DS1<br \/>\n1 x Rocker Switch &#8211; SPST<br \/>\n1 x Resistor 10K Ohm<br \/>\n1 x CR1220 3V Lithium Coin Cell Battery<br \/>\n1 x 1 x Lithium Ion Battery &#8211; 1000mAh<br \/>\n1 x Terminal Block Breakout FeatherWing<br \/>\n1 x SparkFun Cerberus USB Cable<\/p>\n<p><strong>SparkFun Thing Plus &#8211; ESP32 WROOM<\/strong><\/p>\n<p>LED &#8211; LED_BUILTIN<br \/>\nSDA &#8211; Digital 23<br \/>\nSCL &#8211; Digital 22<br \/>\nSW1 &#8211; Digital 21<br \/>\nGPT &#8211; Digital 17<br \/>\nGPR &#8211; Digital 16<br \/>\nVIN &#8211; +3.3V<br \/>\nGND &#8211; GND<\/p>\n<p>&#8212;&#8212;<\/p>\n<p><strong>DL2309Mk05p.ino<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/****** Don Luc Electronics \u00a9 ******\r\nSoftware Version Information\r\nProject #28 - Sensors - LSM9DS1 - Mk11\r\n28-11\r\nDL2309Mk05p.ino\r\n1 x SparkFun Thing Plus - ESP32 WROOM\r\n1 x DS3231 Precision RTC FeatherWing\r\n1 x GPS Receiver - GP-20U7 (56 Channel)\r\n1 x SparkFun 9DoF IMU Breakout - LSM9DS1\r\n1 x Rocker Switch - SPST\r\n1 x Resistor 10K Ohm\r\n1 x Lithium Ion Battery - 1000mAh\r\n1 x CR1220 3V Lithium Coin Cell Battery\r\n1 x Terminal Block Breakout FeatherWing\r\n1 x SparkFun Cerberus USB Cable\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Bluetooth LE keyboard\r\n#include &lt;BleKeyboard.h&gt;\r\n\/\/ Two Wire Interface (TWI\/I2C)\r\n#include &lt;Wire.h&gt;\r\n\/\/ Serial Peripheral Interface\r\n#include &lt;SPI.h&gt;\r\n\/\/ DS3231 Precision RTC \r\n#include &lt;RTClib.h&gt;\r\n\/\/ GPS Receiver\r\n#include &lt;TinyGPS++.h&gt;\r\n\/\/ ESP32 Hardware Serial\r\n#include &lt;HardwareSerial.h&gt;\r\n\/\/ LSM9DS1 9DOF Sensor\r\n#include &lt;SparkFunLSM9DS1.h&gt;\r\n\r\n\/\/ Bluetooth LE Keyboard\r\nBleKeyboard bleKeyboard;\r\nString sKeyboard = &quot;&quot;;\r\n\/\/ Send Size\r\nbyte sendSize = 0;\r\n\r\n\/\/ DS3231 Precision RTC \r\nRTC_DS3231 rtc;\r\nString dateRTC = &quot;&quot;;\r\nString timeRTC = &quot;&quot;;\r\n\r\n\/\/ GPS Receiver\r\n#define gpsRXPIN 16\r\n\/\/ This one is unused and doesnt have a conection\r\n#define gpsTXPIN 17\r\n\/\/ The TinyGPS++ object\r\nTinyGPSPlus gps;\r\n\/\/ Latitude\r\nfloat TargetLat;\r\n\/\/ Longitude\r\nfloat TargetLon;\r\n\/\/ GPS Date, Time\r\n\/\/ GPS Date\r\nString TargetDat;\r\n\/\/ GPS Time\r\nString TargetTim;\r\n\/\/ GPS Status\r\nString GPSSt = &quot;&quot;;\r\n\r\n\/\/ ESP32 HardwareSerial\r\nHardwareSerial tGPS(2);\r\n\r\n\/\/ LSM9DS1 9DOF Sensor\r\nLSM9DS1 imu;\r\n#define PRINT_CALCULATED\r\n\/\/ Earth&#039;s magnetic field varies by location.
