I recently purchased a new Berry GPS-IMU, and connected it exactly as in the tutorials, but the berry doesn’t light up, and the i2c addresses are all empty. I thought it was the solder that was messing up the connections, because at one time it showed all possible addresses in i2c (which when I googled said it is mostly a wiring issue). I removed the solder and tried it again, now it shows nothing. I know the pi is working, because I connected an mpu6050 and it works perfectly. Any ideas?
Edit: When we connect all 4 wires (3.3V, SDA, SCL, GND) to the pi, the pi stops lighting up! I think there are voltage issues. I’m using the Raspberry Pi 3.
It appears that I have the same problem as you with a Berry GPS-IMU regarding the I2C connection, so I was wondering if you managed to find a solution. If so, I would be grateful if you could provide me with some insight.
