Hello, i am using arduino uno,sim7000 and arduino expansion shield. I need to connect a flame and a sound sensor. The only way it's to connect them with the arduino expansion shield and the only way to get everything connected it's to have the sim7000 'up' to arduino and arduino expansion shield up to sim7000.It's like a pyramid. Is it okay if i tried or i might damage the modules?
