This is an update of the original Winkeyer kit that was introduced many years ago and is now back by popular demand. It attaches to a serial port on your PC and does not require a battery or external power source. This makes it very convenient to hook up. The operating current is so low that it can run off the modem control lines of your serial port. These keyers are still finding a place on PCs that do not have USB ports or for remote applications on a network link.
This kit uses the Low Voltage WinKeyer3 CW controller which provides direct paddle inputs and true dual keying port capability. WK Serial runs at 3.3V, which means it will work at a very low RS232 voltage swing like you would find on a laptop PC.
Note that WK3serial is designed primarily to be a host mode device, it can be mounted inside a PC or your own enclosure. Both paddle and speed pot inputs are provided. WK3serial also works great with a USB to serial converter if you want to put together a really low cost WKUSB !
The R02 revision board is very simple to assemble, just solder on the DB9 connector and a 14 pin DIP socket, insert the WK3 serial IC and that's it.
