6.14 GPIO-3 (General Purpose Input/Output) 10pin connector
GPIO-3 connector features the signals of AXP152 on a convenient header. The signals available
might be used to implement power controls on the board – for instance – turning off the device at
specific voltage level or

Signals marked with * are multiplexed with either a peripheral device or another connector. Ensure that the multiplexing is handled
properly on software and/or hardware level (else there would probably occur wrong levels, loss of data, etc).
6.15 LCD_CON 40pin connector
The LCD_CON pins are led out on a separate 40pin connecter for the ease of connecting an LCD.
We have tested the ability of the board to interact with such a display. They allow the user to attach
additional hardware, check readings or perform hardware debug.
