If you do not care about compatibility with existing or potential future boards, we
recommend soldering wires directly to the encoder or installing a standard-length male
header that works better with cables made from our wires with pre-crimped terminals.
A standard-length straight 0.1″ male header allows for compact cable connection.
Once the board is soldered down to the two terminals, the motor leads are connected
to the M1 and M2 pads along the edge of the board; the remaining four pads are used
to power the sensors and access the two quadrature outputs:
The sensors are powered through the VCC and GND pins. VCC can be 3.5 V to 18 V, and
the quadrature outputs A and B are open-drain digital signals that need to be pulled up
to the appropriate logic voltage of your system. The encoder boards have pads for
optional 0603 size surface-mount resistors to pull the outputs up to VCC, but in typical
applications, the pull-up resistors will be on the main electronics board.
