GPIO Switch Bank 2, SW2
GPIO Switch Bank 2, labeled SW2, is a set of five slide switches that set GPIO inputs to
logic levels of high (switch to left) or low (switch to right).
If the GPIO port is configured as an output, then the switch should always be to the left. If
there is an external device connected to P3, the switch should always be set to the left.
Each GPIO port can be used independently.
Notes
1 These switches do not determine whether the GPIO is an input or output. That is
determined by the module software.
2 If GPIO is set to an output by software, switch SW2 must be set to the left (high).
3
These switches are used with the integration kit and the development kit and in
conjunction with GPIO Switch Bank 1, SW1.
Reset, SW3
The Reset switch is a push button switch labeled SW3 on the development board. Pressing
the switch holds the Digi Connect ME embedded module in reset. When the push button is
released, the module reboots.
