Finally, the new generation of the IMU array boards, the MIMU4444v1, arrived yesterday. These boards measure 49.3x26.6[mm] and contain 32 MPU9150 IMUs each, which are all sampled in parallel. The embedded software for the boards is achieved by compiling the code on sourceforge with the argument –DMIMU4444. The design-files for the boards are available under Massive-MIMU. This is not an April fool mockup! The multi-IMU boards are rather a major side project to the main foot-mounted INS development. The same principles are used in the MIMU22BT boards but with 4 IMUs.
