Right now all of the jumpers have the middle pad connected to VDD and the other pads connected through a resistor making this effectively a pullup resistor circuit. In theory you can just pull them down, but you may want to cut the traces first. I&rsquo;m guessing you just need to change the address of one of them. If you still have questions feel free to email our techsupport department and they should be able to walk you through it.</p> Customer #914852 urn:uuid:ef75cc2f-303a-f1f3-2623-608ec4d7992f 2017-03-14T15:31:58-06:00 <p>I recently purchased two of these sensors and I am looking to use them with LabView. I have been made aware that I need to break the solder connection on the back of the sensor in order to have a separate resister. Does any have ideas of exactly what needs to be done and how the resister changes. I don&rsquo;t have much experience with any of this.</p> erich81 urn:uuid:8469ba90-8948-c349-6293-681d76c9c74d 2017-02-13T19:48:43-07:00 <p>just so I&rsquo;m clear, this unit uses the 3 axis gyro to detect true up, vs &ldquo;up&rdquo; of the board/ic, correct? I&rsquo;m looking for something that can identify when it&rsquo;s Z axis is pointed straight to the sky, vs the unit being considered &ldquo;flat&rdquo; in regards to initial calibration, nor it&rsquo;s speed in a direction (similar to gyroscope apps on the android market place) I suppose more of a rotation detection IC?</p> M-Short urn:uuid:dfd045f2-1767-378b-81c3-db67d8e97d0c 2016-08-09T15:14:21-06:00 <p>Looking at the schematic we do have a pullup resistor on the SDO line as it should be tied to something. There is a jumper allowing the user to disconnect the pullup and set the pin to low if they&rsquo;d like. The main advantage to this is if you want to use 2 of these on one I2C bus, in that case you can change the address of one of them. In theory if you get 2 different devices that have the same I2C address you can change one as well, but this is not common.</p> <p>As a general rule you should be able to connect a pin directly to VCC (instead of through a pullup) if there is no chance you will try to pull it down.</p> Customer #651146 urn:uuid:c0c57594-1282-e969-1c64-7e23199339bd 2016-07-24T12:11:42-06:00 <p>Hello, I recently purchased this breakout board and am currently designing a PCB with the LSM9DS1 on its own configured to use I2C. My 2 questions:</p> <p>1) The LSB address select pins (SDO_A/G and SDO_M) does it matter if its configured as high or low or is this simply determining its I2C address which is used in software? What is the purpose of having this selectable?</p> <p>2) I currently have the two previously mentioned pins connected to 3.3v (High) along with CS_A/G and CS_M connected to 3.3v to select I2C. Can I simply connect these pins straight to 3.3v, or do I need to put a pull-up resistor on each? Can I use my MCU&rsquo;s internal pull-up (20 kOhm) and not add any external ones?</p> <p>(This is for the LSM9DS1 by itself, but i&rsquo;m modeling the PCB based on the sparkfun breakout board).</p> <p>Appreciate the help!</p> balam urn:uuid:29e3d156-18d9-1934-7264-f52e50e37440 2016-04-28T11:53:11-06:00 <p>same question here.</p> Customer #26221 urn:uuid:934323dd-8a3a-04ed-5c7c-0f5a06d12dbf 2016-03-30T18:03:29-06:00 <p>Is there any fusion library available which uses all the three sensors to calculate the pitch, yaw and roll with improved accuracy?</p> Customer #505814 urn:uuid:6688fc23-aab4-8a55-193b-5dab6155d683 2016-03-01T13:14:51-07:00 <p>What is the ADC resolution in this thing? 16-bit?</p> DanielChen urn:uuid:21dbddc5-1b5b-eb7c-94e1-e9690be7c25d 2016-02-20T22:34:48-07:00 <p>Whenever I set the accelerometer range to 16 and calculate the magnitude of xyz it gives me ~0.67g at rest (which is obviously wrong) but when I switch the range to 8 and calculate the magnitude it gives me ~1g at rest which is correct&hellip;what&rsquo;s happening when I change the range to 16g?</p> Customer #731552 urn:uuid:31554e5c-7260-be25-dba8-87ede7866aeb 2015-12-07T09:26:24-07:00 <p>Is this IMU compatible with ComMotion Motor Driver Shield?

In the LSM9DS0 the gyro and accelerometer are located in separate sensor devices embedded within one package and have separate FIFO buffers. Practically speaking this means the code is a little different, but I&rsquo;m not sure that you would notice a functional difference. For now I prefer the LSM9DS0 just because it makes it easier to debug or only use one of the sensors if you want to. The LSM9DS1 is a newer device.</p> phuijse urn:uuid:95fb35d7-e6b7-3d6d-ee97-1536ef51ef9b 2015-08-14T08:53:14-06:00 <p>Is there any difference with the <a href="https://www.sparkfun.com/products/12636" rel="nofollow" >LSM9DS0</a> besides size?</p> Customer #46288 urn:uuid:82fc0bfb-fa37-74c9-c746-f6bfa381efe5 2015-08-14T08:45:49-06:00 <p>Is there an AHRS firmware for this board similar to the <a href="https://www.sparkfun.com/products/10736" rel="nofollow" >Razor IMU</a>?</p> Jimb0 urn:uuid:373e98bf-9650-b94b-261f-e0a2247bd471 2015-08-14T08:33:34-06:00 <p>Live now!</p> Customer #365431 urn:uuid:c180dc73-20ea-1525-5615-146ac1653477 2015-08-14T08:23:52-06:00 <p>hook up guide = 404</p>
