Heat-sink as add-on?

[tllim]

@tllim: It would be nice if you would add some docs or wiki or even a small shield plug to power the Pine64 via euler bus - so it is easy for everyone to get rid of the micro USB limitations.

Absolutely second that. BTW: How is correct polarity on the Euler pins to feed DC-IN here?

@tllim: Please think about a modular approach for the Euler connector. If you develop such a shield plug for the Euler connector, please think about preparing a good fan solution also (taking the 5V also directly from DC-IN so the PMIC doesn't have to handle that). Based on my tests (interrupted since fan and heatsink touched yesterday and the fan is damaged now) mounting a fan 10mm above the heatsink and blowing the air away from it showed the best results.

If you make such an Euler shield with a 5.5/2.1 mm barrel plug to be used also with an optional fan please also do consider preparing a vibration free mounting possibility, choose a fan that's silent (diameter as large as possible) and one that can be adjusted through PWM (the necessary 'cooler state' information that can be used to adjust the speed is already available through sysfs now). Combining this with another enclosure variant that would make a nice 'power user' bundle.

(might then look a bit like your Veroboard but with a 60mm hole for the fan, a barrel plug for DC-IN and both connectors for 3-pin and 4-pin fans. And it would be really cool if you not just provide a silent 60mm fan but also search for a laptop fan with same dimensions exhausting the air sidewards so mounting a Veroboard on top would be possible)

We have no plan to make a heatsink with fan support.
