Notes concerning the connection of the PSCusb to your stamp.
To those individuals using the Board of Education, Rev C:
1)
The power source for the servos must be a separate power source from that of the
Board of Education.
2)
Connect the three-pin cable from the PSCusb to X4, slot 15.
3)
Ensure that the Vservo jumper selector, (between X4 and X5), is set to the VDD
position. Connect your servos to the 3 pin terminals provided.
4)
To power your PSCusb, the power switch must be placed to the "2" position.
To all other users:
1)
The power source for the servos must be a separate power source from that of the
5 VDC used to supply the on-board logic.
2)
Connect the three pin cable from the PSCusb to: VDD (Red), VSS (Black), and the
white wire to your choice of I/O pin. VDD must be 5 VDC. Note: the idle state of
the serial line is 5 VDC.
Hardware Reset Pushbutton
The pushbutton on the PSCusb is connected to the reset circuit of the on-board microcontroller. Pushing
this pushbutton resets the microcontroller thereby resetting all parameters to their default values.
