no communication between custom PCB and mpu6050

[Adrian]

Hello,

I used a breakout board of the MPU6050 (playground.arduino.cc/.../mpu-6050.jpg) and the nrf52832 development board. There is communication between the two and I have no problems retrieving data from the MPU6050. However, when I put the mpu6050 and nrf52832 on a custom PCB there is no communication between the two (i.e. no clock signals). The MPU6050 are close to the nrf52832 so there is minimal noise interference. I can provide more information. I'm just not sure what I should add.

Has anyone come across this problem or has ideas to solve this?

Basic questions - have you followed MPU6050 datasheet closely? Decoupling capacitors, pull up resistors on SDA, SCL, correct address (perhaps do a scan across all the I2C addresses to see if that's the problem), etc....

If I remember correctly there's some soldering considerations like not connecting the large pad (may be wrong, but it rings a bell). Checked the soldering in general?
