Hello,The X728 can support the X715. Mount the X728 on top of the X715；need a 2*20 Pin Female Header to increase the height, and need spacers of the appropriate height to hold the X715 in place.
Can you please provide example for how to use X715 together with X728 (UPS) to achieve 6~60V wide voltage input.
I see two options:
1. Stack Raspberry, X715 & X728.
- Power in to X715. X715 will power Raspberry directly.
- Power cable from X715 to X728. For X728 to charge batteries.
2. Stack Raspberry & X728. X715 separate.
- Power in to X715. Fan function not usable as it is not stacked on Raspberry.
- Power cable from X715 to X728. X728 charge batteries and provide power to Raspberry.
- X715 is just used as Buck Converter (6V-60V to 5V).
If I want to use this with the X728, which ports do I use? Do I have plug the 5v output of the X715 into the 5v input of the X728? Do I still stack the hats on the RPI?
I tried this and it works, however when I do this the X728 doesn't recognize when power is disconnected from the X715. If I don't include the X715 in the stack of hats, it does recognize when the X715 is unplugged.
Hello, although X728 can be used together with X715, but it needs to be reminded that if it is not operated properly, it may cause damage. When X728 and X715 are used together, it can only be powered by 2PIN line, not by GPIO. If possible, please provide your order number. If possible, you can provide some pictures (about your question), preferably a video, and send it to our email. Please contact us at support@geekworm.com. We will try our best to help you solve the problem .)
