In addition to headers, multiple test points are located around the board. Black test points (TP22 and TP24-
TP30) are connected to GND, the red test point (TP21) is connected to VDD, and the green test point (TP23) is
connected to VSS. The remaining blue test points (TP1-TP20 and TP101-TP120) are connected along the signal
paths of the pins of U1.
