This is a pre-sale item. We are developing this add-on board and the documentation that should go with it. We’ve had some interest already, so we have decided to see how many people are actually interested enough to be early adopters. This is mainly for those people that want to order one to test it out and see how it works.
This product is for advanced users that are comfortable soldering and tinkering with the Linux code/scripts. Please ask us if you have any questions about this.
The photos/videos shown here are from a test unit. The green wire that runs from “45-SCL” is completely unnecessary. The white wire that runs from “40” is only necessary if you want to program the Pi to turn the fan on/off when necessary. You could also wire it full on or add a switch (on your own) if you want to go that route.
