LA Robotics Club Message Board › Custom Arduino 2560, anyone interested?
Marina del Rey, CA
I've got a 2560 board designed with the following specs:
I'm using it for a project but the more I make the lower the price for me. I'll sell them at cost. Not going to be cheap, but should be sub $200 hopefully. If you're interested let me know.
3 x 30A motor drivers with 4 pin heavy duty connectors
24pin ATX+ 4 pin to connect to PC power supply to power everything
3 chip based encoding counter chips for use with an encoder on a motor (to keep track of motor position)
1 chip for hardware debouncing of 5 buttons (software debouncing sucks as you'll find out)
DB25 connector with 5 digital pins (220 ohm resistors on-board for driving LEDs) and 5 analog connections. This allows you to connect those over a regular parallel port cable.
Micro SD card reader
All unused pins are put on headers, does not use a standard pin layout so traditional shields don't directly plug in but could with cables.
If you want a lot of features on one board that will give you a lot of power and flexibility this might make sense for you.
