For all headers J1 through J16, the connections are the same, but are rotated by a multiple of 90° according to
their position on the board. A legend is included for each rotation.
In addition to headers, multiple test points are located around the board. Black test points (TP18 and TP20-
TP26) are connected to GND, the red test point (TP17) is connected to VDD, and the green test point (TP19) is
connected to VSS. The remaining blue test points (TP1-TP16 and TP101-TP116) are connected along the signal
paths of the pins of U1.
Table 4-2 shows the test point connections.
