I've updated the "Full download" with more Information on the Programmer board and the installation of the Driver for the board, this is in the "Nano Board Info.pdf".
I've also include the Driver Install application in the ZIP.
FYI: The Toroid rings I used for the last two chokes are AS225-125A ferrite toroidal rings.
I ordered some more just in case from a different supplier, these arrived correctly packed, each ring bubble wrapped and all rings packed in a large box with bubble wrap inside. Ordered on the 14th Feb and delivered today 25th Feb.
AS225-125A ferrite toroidal rings AU-$7.47 inc tax, free shipping.

Ideally you want 9 of these rings for a single 4 turn 23uH high saturation choke. A smaller inverter could get away with six per choke and another turn or two.
NOTE: You need two chokes per inverter, yes the inverter will run with one choke, however two chokes of 23uH each reduce the size of a single 46uH choke choke, most LF Inverter will require a total choke inductance of 39uH to 46uH.
