The buffer board have gain, to end up with the standard 2V RMS single ended output.

But you can do whatever you want, use it or not, or change the gain, schematics and BOMs for the accessory boards are up on soekris.dk

You can also reduce the output level with no side effects by a resistor from output to ground, the direct resistor networks output is a voltage source with 625 ohms output impedance....

**** NEWS ****

The dam1921-02 and dam1941-12 are now shipping from me. The online shops should get them soon, the soekris.eu shop will already have them tomorrow Friday, so some people might see them Monday....

As said earlier, we also have the set of bare accessory PCBs in stock, those who ordered before today will get the set for free.

I'm working on the manual, we be ready over the weekend.

Sören,

I have a few questions:
  1. If I do not use the display board in the kit, am I then correct that the VCC5D consumption remains 350 mA (can i ignore the 150 mA for the example display)?
  2. How much current does the included output buffer board use?
  3. Is the serial port on the DAM1941 (J8) isolated?

Søren,

1.Will you release 1941's uC source code? That may help me to design my display board without another controller.
2.Does XFeed select or Output select can be controlled over the Serial Port?

thanks.
