Grove - 6-Axis Accelerometer&Gyroscope (BMI088): Layout mistake

Hi

There seems to be a mistake in the board layout for the BMI088 Grove sensor.
The jumper for the accel address is non functional because the trace AD0 is directly connected to the Pad11 (pullup) instead of the middle Pad.

So the Low address (0x18) cannot be selected.
Am i the first to use two of those IMU on the same I2C bus?

Hi @dworz
Yes, you are right. Our schematic has no problem, but the layout was wrong.
If you want to use the low address(0x18), you have to cut off the connection between AD0 and PAD11, and then connect the PAD11 directly to the GND on the other side with a flying wire.
