    After hearing about the Powercell getting toasty, I think I should add one of these...

    Do you recommend its use for Raspberry Pi?

    How are these attached? Received them but there is no adhesive of sorts.

      I had to buy some heat sink tape

      • jumptrader / about 11 years ago / 1

        Did you attach it to the chip itself? Or the underside?

        • Member #269718 / about 11 years ago / 1

          heat sink tape is like 2 sided tape. it can be applied to either heat sink or chip first. It is easier to put it on the heat sink and trim it first.

            Thanks. I ended up getting some thermal adhesive! Works well.

    A little bit short to properly sink the Pololu DRV8825 but it should still work. For the price I'm a little upset that it does not have heat sink tape with it.

    This is a great idea for a current heavy H-bridge motor driver. Need to get these back in stock.

  • jago lee / about 11 years ago / 1

    Would this sink the raspberry pi?

    • MostThingsWeb / about 11 years ago / 1

      Robert suggested that they might carry a heatsink specifically for the raspberry pi.
