  • I have been successfully using this converter for a while on 3.3V and 5V boards, but today I struggled to get it working on a 1.8V board, the RX led is too weak and I don't see anything on the other side.

    Have anyone tried this on a low-voltage board? I just one to discard this before looking for errors anywhere else

No public wish lists :(
