(UK) Heatsinks for Duet3 driver chips

[JuJuDelta]

Hi,

Where can I get a bag full of heatsinks I can stick on the Trinamic 5160 stepper drivers chips, and what footprint size should they be ?

Thanks.

@JuJuDelta Why would You want to cool TMC5160 when they have external mosfets?

The driver chips don't need heatsinks. If you need extra cooling, use a fan to blow air lengthways along the board, especially the back.

Doh ! Yes of course, just looked at the schematics !
(Must have been thinking about another older project)

Thanks, I''ll arrange for a gentle breeze for the 1 x 6HC, 2 x 3HC, 4 x 1XD
