ISP
Target
Interface
The
target
connection
interface
is
configured
to
supply
3.0
Volts
to
the
target
and
meant
for
direct
connections
to
the
MeshConnect
IC
or
module
pins.
Interfacing
directly
to
an
RS
‐
232
line
driver
IC
will
not
work
and
will
most
likely
damage
the
MeshConnect
ISP
/
WNA
USB
dongle.
Prior
to
programming,
it
is
strongly
advised
that
any
circuitry
on
the
target
board’s
UART1
or
GPIO
pins
be
isolated.
Pin
#1
on
the
connector
is
found
on
the
RED
side
of
the
target
cable.
The
target
cable
has
the
signal
pinout
as
shown
in
Figure
20.
