What I currently look at: Invensense has its MPU 9250 coming up, which could be a nice replacement for the MPU-6000 6DOF Gyro/Acc and HMC5883L Compass in one chip package. So, less PCB space occupied and less different parts to source as well as a simpler serial protocol. Looks like the future IMU for quads! Also, I like the new ublox GPS module with an integrated patch antenna, the PAM-7Q. Too sad I am not a facebooker, so I can’t press any like buttons for that one. Both the Invense IMU and ublox GPS are upcoming products which can not be sourced yet, so there a nice candidates for an upcoming design.
