An example of a stand alone application for the DT207:
1 by DT207 PCB
1 by 7805 +5 Voltage regulator in TO-220 case.
1 by Suitable heat sink for above Regulator.
1 by Diode Bridge D1 WO2 (or WO4 type)
1 by 2.1mm or 2.5mm DC Input plug. PCB mount.
1 by Capacitor C1 1000uf Electrolytic @25 Volts. (PCB type mount.)
1 by Capacitor C2 .01uf (or .1uf) Ceramic
1 by Capacitor C3 .01uf (or .1uf) Ceramic
1 by Resistor R1 330 .25 watt Red LED 1
1 by Resistor R2 330 .25 watt for Reset Switch.
1 by 5mm Red LED. LED 1 PWR monitor
A Reset switch can be added for CPU control,
This can be a mini 2 pin TACT switch that can have a .2" or a .3" pattern.
1 by MAX-232 or equivalent.
4 by 1uf Electrolytic or Tantalum Caps for Max-232. C4 to C7.
1 by DB-9 female right angle PCB mount connector.
It may also pay to install a 16 pin socket for the Max-232, as you may choose to remove it for some configurations.
My Apologies, two board faults have been found:
You can also use a small pair of long nose pliers to squeeze the widest part of the pins, so that they will fit through the board. Trim the legs at approximately the correct length before trying to force the pins through the board. Again, bend the legs at right angles before doing the above, so you can guage were to cut the legs off.
