Mounting Kits for Picos


As part of my Pico development fun, I would like to have the appropriate screws and risers to attach various components to the board. I bought the M2.5 mounting kit which fits the small holes on the FEETECH FS90R Micro Continuous Rotation Servos.

I would like to know the exact size for the HC-SR04 Ultrasonic Module Distance Measuring Sensor as well.

For the GlowBit 8x8 Matrix Mounting Kit it doesn’t list the size, but these seem to be the same size as the Pico itself. Do you have larger kits that fit the Pico holes?

When I use my callipers to measure the M2.5 screws, it says 2.0 on my readout, so I don’t really trust myself to just order a kit without confirming with you first what will fit.

Thanks in advance!

Hi Timothy,

The GlowBit 8x8 Matrix Mounting Kit uses M2 fasteners.

The holes in the corners of the HC-SR04 Ultrasonic Modules are tooling holes used by the machinery that assembles the modules. I’m not sure exactly what size it is, but it’s smaller than M2, so a header pin soldered into it is likely the smallest fastener you could hope to get which fits it.

Thanks Trent.

Just in case it helps anyone in the future, here is what is recommended so far:

  1. White Nylon Screw and Mounting Kit -M2 SKU: FIT0666
    This size fits the GlowBit and Pico holes.

  2. White Nylon Screw and Stand-off Set – M2.5 Thread
    This size fits things like the FEETECH FS90R Micro Continuous Rotation Servo and is suitable in general for the Piico Dev components.

  3. Smaller than M2 size is required for the HC-SR04P(opens in new tab) or HC-SR04+(opens in new tab) Ultrasonic Sensors. Trent has recommended header pins soldered into the tooling holes for these.
