The external pressure on the chips of board minimu-9

Hi,

Currently I am customizing some enclosure the the board minimu-9 (pololu.com/catalog/product/1265). My question is that if I design the enclosure with a very tight space, then it may cause some pressure from the case onto the chips of board minimu-9. I just want to know whether it will impact the output of the acc, gyro and mag? Thanks!

Hello.

We do not have the MinIMU-9 characterized that way, but I do not recommend applying a pressure or force to the board. It might have some effect on components on the board. I recommend reading through the datasheets under the Resources tab on the product page and seeing if they give any specifics on allowable mechanical stress.

Just for those who need to design the enclosure for this sensor information:

I tested the effect of applying external force onto the sensor board. I found that the bias of the gyro reading was changed a lot when there was a force onto the board, while the accelerometer seemed ok to this force. So when designing an enclosure for this sensor, don’t let it directly contact the sensor.
