3.7.16 Sensor IO Expansion Header J2100 (25)
Figure 19. Sensor Expansion Header J2100
The sensor expansion header J2100 allows for a 24-pin connection to an optional sensor board. If user
application does not require a sensor, then this header can be used for other applications that require I2C, SPI
or GPIO input and output connections. Following is the pin breakout for sensor expansion header J2100.
