== GPIO GPIOs ==== Optional GPIOs == All the optional SODIMM pins can be used as GPIOs . The following table shows some recommended SODIMMS pins to be used as Keypad GPIOs:{| align="JUSTIFY" cellpadding="1" border="1" style="width: 300px; height: 1px;"|-| '''Name''' | '''SODIMM pin''' IGEP COM AQUILA contains a Keypad peripheral. The Keypad Port is designed to interface with the keypad matrix. It| '''AM335X pin'''s designed to simplify the software task of scanning a keypad matrix. With appropriate software support, the KPP is capable of detecting, debouncing, and decoding one or multiple keys pressed simultaneously on the keypad.* KEYPAD_COL:|-| KP_COL0| 72| U16|-| KP_COL1| 73| C12|-| KP_COL2| 74| C18|-| KP_COL3| 75| U18|-| KP_ROW0| 77| A15|-| KP_ROW1| 78| D14|-| KP_ROW2| 79| V12|-| KP_ROW3| 80| T13|-| GPIO0| 148| V14|-| GPIO1| 149| U14|-| GPIO2| 150| T14|-| GPIO3| 151| U15|-| GPIO5| 153| T16|-| GPIO6| 154| V15|-| GPIO7**| 155* KEYPAD_ROW:| R14**|}
