WinKey USB SMT Assembly Guide Version 1.5 12/26/2017
This document describes the assembly and testing of the K1EL Winkey USB Keyer Kit with a
version 01 SMT PCB. In this new design, surface mount components were used where ever
possible. These parts are pre-soldered to the PC board and tested at the factory. Assembly is
fairly simple and consists of soldering a few switches, connectors, and two wires. The builder
then performs final assembly and testing. Please read instructions before starting, there are
several steps that must be followed exactly as described.
