SCM20260E Open Drain Outputs

Hello again,

We are currently addind a 4G LTE module into our design and we need an open drain port to correctly drive PWR_ON and RESET pins to boot the module.

Is there any way to set Open Drain modes for the SCM20260E GPIO pins? If so, how can this be done?

Thank you.

Use an NPN transistor. You’ll probably find that the design specs for the modem indicate this as the preferred option. The modem is likely to be a different voltage than 3.3V so watch for this for some of the IO Pins.

Hi, there is in GpioController class.

SetDriveMode(GpioPinDriveMode.OutputOpenDrain);
