THIS IS A DRAFT AND COMPLETELY UNTESTED.
|
|
|
|
The extension board is meant to connect to a 50 mil ribbon cable,
|
|
which in turn connects to a connector for a 7x2 100 mil header.
|
|
|
|
To reduce crosstalk, signals are always separated by ground. We
|
|
cannot use VDD for crosstalk suppression, because the device may
|
|
be self-powered and VDD would thus be disabled.
|
|
|
|
If the connector is reversed, VDD is shorted to GND.
