Mpu 9150 stm32?

Question

Electronics

Good afternoon. I can't start mpu 9150 via i2c with stm32f4discovery. The module is working. C raspberry pi works well, but not with discovery. Please help, can anyone have a working code or project

Answer 1

I'll assume it's stupid, but still:
Are you supplying power from the Discovery board to the module? If I'm not mistaken, the discovery works on 3.3 volts, and on the sensor board (which you have in the photo) there is a power stabilizer installed. If you feed the board from 3.3 volts, the stabilizer puts all the voltage on itself and its output is crap. The sensor board must be powered by 5 volts. Maybe because of this cant?
