Nope... only one Movement Panel per project.... You'll still need to script the second controller whether it be a sablertooth or a standard H - bridge...

Just throwing this out there as another option, and it really depends on how interdependent the functions are, but if you really think you need two movement panels for some reason, you can run multiple instances of ARC on the same computer, each with its own Movement Panel (of course, you'll also need multiple EZ-B's unless one of the instances is driving a compatible 3rd party robot like a Roomba).

Scripting probably meets 99% of the needs though.

I have been following this thread and I also have a question...

How many serial devices can I use with the EZ-B? For example how many Sabertooth drives could it handle?

Every digital port can send serial, so lots... If you need to receive serial, than D0 plus the other two UARTS.

@rgordon... For sending and receiving there are 3 UART ports... For just sending, I believe you can do that on all 24 digital ports.... so 24 sabertooths if you don't need feedback...

Edit Rich is correct 25 ports for sending....

25 on the V4 if it is send only. 3 are bi-directional (however 2 of those take up 2 ports). 20 on the V3 however it is send only on all ports.

Looks like three of us posted at around the same time

@Alan... Can D0 send and receive? I thought UART port 0 was a dedicated 4 pin port, UART #1 is D5,D6 and UART #2 was D18,D19...

No D0 can't, it's UART0 (the dedicated port), UART1 (D5/D6) and UART2 (D18/D19) which are bidirectional.

Throw in a PIC or Arduino and you can use the I2C port for serial communication too, which would increase the number to a lot
