USB to Rig Interface and CW keying II

The prebuilt FT4232H mini modules are small.

In the photo is £1 coin for size comparison.

Just adding a few jumpers and using a a small USB cable and the unit added 4 COM ports to laptop. Going to build up a PCB using daughter boards to add 4 TSSOP MAX3243 RS232 line drivers and 4N25 optocouplers. Farnell have also furnished the 6 and 8 pin sockets for FT897 and FT817 CAT and Data connections.
