Digital and Analog I/O
5.1
GPIO (General Purpose Inputs and Outputs) Configuration
The ZE10 module has total 14 I/O pins. Among these pins, I/O pin 6 is assigned to factory reset only and
the user can use the rest 13 pins for general purpose inputs and outputs. The I/O pin assignments are
shown in Table 5-1. As shown in Table 5-1, some pins provide special functions built into the firmware.
Table 5-2 describes the special functions tied to the specific pins.
