Hardware

5.1.4.3 PSoC 5LP GPIO Header (J8)

An 8×2 header is provided on the board to pull out several pins of PSoC 5LP to support advanced

features such as a low-speed oscilloscope and a low-speed digital logic analyzer (see Figure 5-10).

This header also contains the USB-Serial bridge pins that can be used when these pins are not

accessible on the Arduino headers because a shield is connected.

Note: You can use PSoC 5LP for your own custom firmware. See Developing Applications for PSoC

5LP on page 134 for details.
