Will this one do? https://www.sparkfun.com/products/12731
Thanks in advance!
The first one (the cable-adapter) use as-is, with only Tx, Rx and Gnd connected.

The second one (which may be too big to get inside the case) -
See on the schematic where VCCIO is connected to switch, giving choice of 3v3 or 5v0 operation?
Disconnect that, bring out the VCCIO lead to the I/O voltage reference from the Kindle (then it will work 1v8 also).

You might double check that in the part datasheet - that the device will work at 1v8 if you use an external reference.

I just noticed myself that "Jim" is out of stock (again) - -
Maybe an e-mail campaign would help get him moving on re-stocking that board.
