The MigProg is USB to serial converter which provides a TTL signal, 5 V power supply and a auto-rest-signal. It comes as a ready to use pre assembled programming tool for the Mignon Game Kit.
10,- Euro
In addition to other USB to serial tools MigProg is very easy to use, because it visualises all processes with three LEDs (Power, TX and RX).
A important advantage of MigProg is safety. Two fuses are protecting the computer and a transistor interrupts the power supply, in case it is not supported by the software.
MigProg comes inclusive cable.
