Which MPU9250 breakout and which MCU?

Hi! I can't get my arduino to detect my MPU9250. I added 2 4.7k resistors on the SDA and SCL whilst to VCC(3.4 v) . I've tried almost everything but I cant get it to be detected. the I2C scanner can't detect it on the addresses. Occasionally, I get the first line of all the codes and a seemingly endless "Scanning...." I used the basicAHRS code but didn't get anything on the serial monitor. I tried using 5V on it too because It had a voltage regulator on it(not for sda and scl). I tried running without the pull up resistors and vcc and without vcc aswell but nothing seems to work. Any help would be appreciated!

Hi Kris,
It's a GY-9250(that's what it says on the sensor)
And here is how I connected It EXCEPT the CS and SD0
Thanks for the reply! But I'd really appreciate it If we sort this out.
Did you pull nCS up to enable I2C?

Hi Kris, I didn't do It I guess.
EDIT: I tried it and it still didn't get detected on the I2C scanner.
Yes.

Hi! I can't get my arduino to detect my MPU9250. I added 2 4.7k resistors on the SDA and SCL whilst to VCC(3.4 v) . I've tried almost everything but I cant get it to be detected. the I2C scanner can't detect it on the addresses. Occasionally, I get the first line of all the codes and a seemingly endless "Scanning...." I used the basicAHRS code but was blank on the serial monitor (with the display lines). I tried using 5V on it too because It had a voltage regulator on it(not for sda and scl). I tried running without the pull up resistors and vcc and without vcc aswell but nothing seems to work. I even tried running it on my mega board instead of the uno but that didn't work. I get 2.6 volts on the SDA and SCL without the pull ups and Vcc's and 3.5 with them. I've tried connecting INT aswell but that didn't work either. I am a noob at this. 3.3V - Vcc GND - GND SCL - SCL or A5 SDA - SDA or A4 NCS - None INT - None or specified pin Any help would be appreciated!
