Motors do not vibrator BLE 33 Sense + DRV2605L

Hi I have a simple setup trying to run the basic example in Adafruit_DRV2605 library. However the motor does not vibrate as what I would expect. I am following the Adafruit steps except I did not solder them together:

Here is what I have:

  1. BLE 33 Sense
  2. DRV2605L Adafruit Board
  3. ERM motor linked on Adafruit that suppose to run between 2-5v
    Picture for setup:

After loading the simple example, it suppose to iterate through different vibration patterns but the ERM motor is not moving at all.

Here are the debugging I tried:

  1. Replaced the setup with Arduino Uno Rev 2, still not vibrating
  2. Replaced the DRV2605 board with 2 other boards, still not vibrating
  3. Replaced the ERM motor with 2 other motors, still not vibrating
  4. Connect the ERM motor to 3.3v power, it vibrates
  5. Used multimeter to test VIN and GND on DRV2605 and it shows 3.3v
  6. Used multimeter to test + and - on DRV2605 (Where I should solder the motor) and it is always 0v

Any pointers on what might have gone wrong? Although they are not soldered but the multimeter is showing readings/no readings so would that make a difference?

It is essential to solder the pins on the motor driver. On any module, in fact.

There are good soldering tutorials on line -- try Adafruit and Sparkfun.

It sounds like it is not connected properly. Post a schematic, not a frizzy thing showing exactly how you wired it and links to the hardware parts giving technical details.
