I2C Module Problems with Grove Beginner Kit for Arduino

Products & Technology Grove
12

I soldered the 3.3 v connection as in your diagram.
Now this i2c scanner sketch finds the accelerometer board.

However, the “Sensing Movement” sketch outputs:
x:-0.20 y:0.10 z:1.00
LIS3DHTR didn’t connect.

Is this sketch working for you?
(It worked before I removed the accelerometer module from the board.)

Can’t get the Air Pressure Sensor(BMP280) sketch to work after removing the accelerometer module.
Hangs on “bmp280.init().”
Wondering if Seeed Studio actually tested this product by removing the modules?

Perhaps there is some sort of problem with I2C termination resistors when the module(s) are removed from the board?

Thanks,
Wayne
