Hi there I have some question also regarding the BOOZ_IMU, so it can connect directly to TinyV.2.11? but from the Sch, it need to supply 6.5V? or it is better to connect BOOZ_IMU to BOOZ_main ? From what i guess when i read though all the sch, Booz_main is the controller, which connect to IMU and GPS (the gps for booz), am i right ?
