The total cost comes to about $4.50 which is more tha=

expected, but i can get it lower using slightly different parts.

It runs as a normal NV neuron but there are a few thi=
ngs, =
jumper A is designed to give bias, you can adjust the pot to the value yo=
u =
want (0 ohms if you want) then you use the two pins to add whatever bias =
you =
want, also handy cause you can just plug it in using a connector. When yo=
u =
aren't using the bias, set the pot to the value you want and use the jump=
er to =
join the resistor to ground.
Jumper B has three headers. The first is to con=

your output to (motor driver). The next two allow you to turn on or off t=

LED.
The 'board in' Connector (male) is located on the sid=

output from the previous neuron to the input of the current one. The spar=

how to use it (bias, sensors, data bus).
The 'board out' connector (female) is pretty self =

The spare connector is the same as above.
Boards can either be connected directly side to side =

a cable. Power only has to be provided to one neuron, which could be done=

soldering wires onto the power pads, or i could add connector (but theres=

enough already).
The whole thing would be surface mounted to a small P=

blank connector boards but that just adds to cost and complexity.<=

What do you think?
