Common Parallax Stamp Issue Summary
Page 18
The following photo shows a complete setup of a Parallax “Board Of Education”, wired to a BiStepA06
board.
A “zoomed in” image shows the signals a little bit more clearly:
Observe that the ground between the boards is accomplished by a wire from the extra “GND” connector on
the BiStepA06 power connector (lower right of board as shown) to one of the “Vss” signals on the BOE.
Also observe that the P1 SO, P2 SI, and P3 RDY signals actually go “straight across”: the signals line
up in a set of rows.
