Can I connect the pin of an STM32 microcontroller directly to the PWRKEY pin of the MC60 module without using a transistor, and successfully turn the module on and off?
Would this cause any issues?
I’m designing a device intended for mass production.
It is not recommended to directly connect the GPIO of STM32 to the PWRKEY pin of MC60 module, as the voltage source of PWRKEY in MC60 module is VBAT (4V), which does not match the voltage domain of STM32. It is recommended to use OC circuit control
