Do you have any hubs left? A couple of chips on mine fried on Friday. Seems the issue was that the DC-DC power supply for the hub has gone and allowed full battery voltage through to the hub which it obviously can’t handle. If you’ve a Batch 4 hub available I’d really appreciate it. Can power it with a separate battery rather than the DC-DC converter if those are a problemo.
Fried chips
Cause of fried chips. Testing the power supply and the output side is showing the full input voltage.
