Replacing ATmega328 with a better microcontroller smd

Projects General Guidance

Hi,

After all that time arduino hobbyist i worked only with amtega328 not the smd one,
and I got new project coming and coming and using only 328 it's nice but i make more
and more complex circuits and using I2C because i don't have the necessary pins.

So i thought to upgrade to a better and more pin chip that will give me more pins and using
only one chip per project instead of 3 as i used to do till now.

Ofc I need something smd and easy to solder, i build my own PCB's always,
the upcoming project i need 12 Digital pins and 6 pwm pins as well free pins mosi,miso..etc
to connect a nRF24.

Any suggestions?

Have a look at the ATmega640... series, with 54/86 I/O lines in 64/100 pin cases, as used e.g. in the Arduino Mega.

Some People would assert that "something smd and easy to solder" are opposites of each other. SMD "can" be what some People refer to as "easy". Myself, I find it hard to do.
Good luck with the Project!
