Components

The PWM3360 has exceptional capabilities: high motion detection under speeds of 635 cm/s, and can deal with accelerations up to 50G. The register outputs the SQUAL value, a reference of the quality of the surface. The sensor is available for purchase from JACK Enterprises in Tindie [1]. In order to control it you will need to download the library PWM3360 from Sunjun Kim [1].

The breakout board has the essential pins available and distributed in a way that makes it easy to connect:

  • VI = 3.3V
  • MI = MISO0 -or- DIN
  • MO = MOSI0 -or- DOUT
  • SC = SCK0 -or- SCK
  • SS = CS0 -or- CS
  • GD = GND

The holder can be quickly 3D printed (STL file and STP file) and can be used with the Thorlabs parts described for the other sensors (ADNS 2610 and 3050). To attach the sensor with the holder only two M2.5 16 mm pan head screws and two M2.5 nuts are needed. The nuts can be pressed to fit on the holder and the bolts will hold the lens against the sensor without the need of glue (Figure 1):
