The total cost comes to about $4.50 which is more than =
i =
expected, but i can get it lower using slightly different parts.

It runs as a normal NV neuron but there are a few thing=
s, =
jumper A is designed to give bias, you can adjust the pot to the value you =
want =
(0 ohms if you want) then you use the two pins to add whatever bias you wan=
t, =
also handy cause you can just plug it in using a connector. When you aren't=
=
using the bias, set the pot to the value you want and use the jumper to joi=
n the =
resistor to ground.
Jumper B has three headers. The first is to conne=
ct your =
output to (motor driver). The next two allow you to turn on or off the =
LED.
The 'board in' Connector (male) is located on the side =
of the =
board, it provides power from the previous neuron. It also gives the output=
from =
the previous neuron to the input of the current one. The spare connector (w=
hich =
has a jumper) can be used for any cross board application, it's just an =
auxillary to add more functionality, use your imagination on just how to us=
e it =
(bias, sensors, data bus).
The 'board out' connector (female) is pretty self expla=
natory. =
It has two power connectors to pass power to the next neuron. Also has the =
output from the current neuron to give to the input of the next. The spare =
connector is the same as above.
Boards can either be connected directly side to side or=
with a =
cable. Power only has to be provided to one neuron, which could be done by =
soldering wires onto the power pads, or i could add connector (but theres e=
nough =
already).
The whole thing would be surface mounted to a small PCB=
, in =
the shape of a triangle of hexagon. That means that eventually cables will =
be =
required or connectors used on multiple sides of the PCB. You could also ha=
ve =
blank connector boards but that just adds to cost and complexity.
