and insert the long ends of the
male headers into a breadboard
11. Place the inverted 4x4 piece of
stripboard on the short ends of
the header pins so that the pins
protrude through the end holes
of each trace (see Figure 10).
12. Solder the short ends of the pins
to the 4x4 sandwich board. At
this point, you may want to snip
the protruding pins from the top
of the sandwich and file them
smooth — especially if you intend
to paint them later.
13. Remove the board assembly from
the breadboard and insert the
resistorized LED as shown in the
layout. (Be sure to observe the
14. On the bottom of the board,
bend the lead from E5 and snip it
so that it makes contact with the
header pin at E4. Press the lead
flat against the traces and solder
the leads at E4, E5, and E6.
15. Insert the switch and solder its
leads at C4, C5, and C6.
16. On the bottom of the board, file
all the cut leads smooth.
17. Clean the flux from the bottom of
the board and allow it to dry.
18. Inspect the board carefully for
accidental solder connections
and other problems.
To test the completed AxMate
adapter, simply insert it into the end
of a breadboard (so that it straddles
the center divider) and connect it
to your computer with the FTDI
cable or one of the USB to Serial
adapters we discussed earlier. On
the breadboard, make the
connections as shown in Figure 10.
Before you include the 08M, turn
on the AxMate’s switch and use a
multi-meter to test the power and
ground connections on both
