Greetings All, Simply, I have an atmega128 5vdc chip I need to serial comm to a 3.3 wifi module. I have been told I need something like a max3232 chip to do the conversion. I've read the data sheet on this chip and am not certain it meets my needs nor what would be required wiring it in. Can anyone point me in the right direction, maybe a schematic of a proper hook up?
