My MCU 's gpio pin can output 3 volts. I need to output 4.2 volts for a certain signal. The pin can toggle at a max of 10Khz.
I was wondering if i could use the 2N3904 switching transistor for this purpose and drive it from the gpio pin. I don't want to use a cmos-ttl converter chip because it's just one pin's voltage that i need to boost. Is this the right approach?
