is this type of shield available?

I have a shield similar to this Screw shield

But what I really need a shield that will let me add line drivers to some of the digital pins and then connect those amplified signals out through the screw terminals.

Hi,

We have those shields HERE:

You can see the PC board traces that go from the Arduino connectors to the screw-type terminal blocks.

You would have to cut the traces for the pins you want to rewire with drivers etc. Then you'd need to mount the driver chips in the center proto-board section, also connecting power, ground and adding decoupling capacitors (probably 0.1 uF) to each chip. Then wire the driver inputs to the arduino pins and the driver outputs to the Screw terminals.

Otherwise you would need to design a new board altogether.

DISCLAIMER: Mentioned stuff from my own shop...

Thanks.

Since I need 3 screw terminals in addition to VCC and GND, it looks like I can use

(1) the Freetronics Terminal Shield http://www.freetronics.com.au/collections/protoshields/products/terminal-shield-for-arduino

or

(2) the Sparkfun ProtoShield kit SparkFun ProtoShield Kit - DEV-13820 - SparkFun Electronics and add some 0.1" screw terminals https://www.sparkfun.com/products/10571

I don't see the traces on the PCB that I have.

Buzz them out to make sure. The wire up the female header to your driver and out to the screw terminal.

The connection is pretty much 1 to 1.

The problem is that my PCB is dark blue, and the traces are not on the bottom of the PCB.
The traces are internal.
