sparkfun electronics pimoroni fan shim for raspberry pi sparkfun <p><strong>description: </strong>make you raspberry pi 4 seriously cool with the fan shim from pimoroni! this 30mm no-solder, controllable cpu fan with rgb led and tactile switch will give your raspberry pi significantly better thermal performance. it's whisper-quiet too!</p><p>the fan shim uses a friction-fit header, so it just slips onto your pi's pins and it's ready to go, no soldering required! note that, due to the height of the fan, if you want to use hats or phats with fan shim, then you'll need to use a booster header. the fan can be controlled in software, so you can do crafty things like toggle it on when the cpu reaches a certain temperature. use the led as a handy visual indicator to show fan status, cpu load/temperature, whatever! the tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode.</p><p>** note:** not heatsink-compatible. when mounting or detaching the fan, or assembled fan shim, do not push on the fan itself, as it is liable to break.</p><p><strong>features: </strong></p><ul><li>fan shim pcb</li><li>30mm 5v dc fan with jst connector</li><li>m2.5 nuts and bolts</li><li>30mm 5v dc fan</li><li>4,200 rpm</li><li>0.05 m3/min air flow</li><li>18.6 db acoustic noise (whisper-quiet)</li><li>friction-fit header</li><li>no soldering required</li><li>rgb led (apa102)</li><li>tactile switch</li><li>compatible with raspberry pi 4 (and 3 b+, 3 a+)</li><li>python library and daemon</li></ul>
