I am designing a hardware for my product using Pi CM4.
In the datasheet, the information about WL_nDisable is:
"This pin serves a number of functions;
1. It can be used to monitor the enable/disable state of wireless networking. A logic high means the wireless
networking module is powered up.
2. When driven or tied low it prevents the wireless network module from powering up. This is useful to reduce power
consumption or in applications where it is required to physically ensure the wireless networking is disabled. If the
interface is enabled after being disabled, the wireless interface driver needs reinitialised."
So, I want to display the status by LED so I plan to use WL_nDisable to connect to Gate pin in N-channel mosfet in high site circuit, is it valid?Or is there any other solution, please help me!
