Channel Breakout, Power Breakout Boards

 

Power Breakout Board, comes with mosfet polarity protection. No onboard regulator, intended for projects that have a dedicated high wattage supply already (no puny 7805).

 

 

Channel breakout board, supports up to 16 ports (Supports servos too), and powered by the connector on the right hand side, therefore you can power them off their own dedicated supply.

Botboarduino drivers

Ok guys it's been a while since I've been on I'm glad everything is picking back up.

I recently had to wipe my computer after getting a virus. Which means I lost all my drivers and code and etc. I managed to get arduino up and running but my botboarduino needs drivers to work. I'm kinda freaked out about catching another virus and I can't seem to find the correct drivers for ft232 uart. I tried one place but it keeps asking me for a password to open it. And when I point the device manager it refuses to see the zip file.

A single artificial neuron can represent some simple Boolean functions like OR, AND or NAND and some like XOR not, because a single artificial neuron can only learn linearly separable mappings.

Example. Perceptron for the AND function:
