Attiny85 or Arduino Pro Mini?

Hi,everyone.

I am planning to start a project. Controlling RGB LED using Arduino with a 433mhz transmitting and receiving module. For the transmitter, I planned to use a Arduino Uno which has been laying around for a long time. Here the problem came. For the receiver, should i use a Attiny85 or a Arduino Pro Mini ? The receiver should be small enough so that it can fit on a chassis i designed. In my opinion, Attiny85 is cheaper and smaller in size than the Arduino Pro Mini. But Arduino Pro Mini have more output pin than the Attiny85 which gave me more spaces for upgrading. The Pro mini also have a larger range of Input Voltage.

Any Suggestion ?

Thanks.

It's just a matter of design. An ATmega85 has limited outputs, limited RAM, limited Flash, limited speed and also a smaller set of libraries because not all are made to work. So really the rest of the design requirements will determine what is a better option.

So what is powering it? What exactly do you want to drive (addressable, mosfets, multiple strips etc)? What else do you might want to connect? What transmitter? What protocol?

How big is your sketch for the receiver? With an RF lib and LED lib you prob won't get it to fit on an ATTiny85.

I use an ATTiny85 with RF and single color LED strips myself.
