Arduino Pro Mini + Signal Generator Sheild

Development Boards Arduino
1

Hi there,

I’m interested in the Mini Gen - Pro Mini Signal Generator Sheild and Arduino Pro Mini combination. I’ve got a few questions:

  1. Are these low power?

  2. Does the Arduino Pro Mini have enough onboard memory to remember the programmed frequency and some bits and bobs? Will the signal generator, output the programmed frequency on power cycle?

My application is to generate a frequency in KHz range and to switch this on and off periodically.

Regards,

Amin

Hi Amin.

  1. Are these low power?

This board isn’t designed to be a ‘low power’ board but shouldn’t consume too much current. Check the datasheets for the parts used on the board to get an idea what current they require.

  1. Does the Arduino Pro Mini have enough onboard memory to remember the programmed frequency and some bits and bobs? Will the signal generator, output the programmed frequency on power cycle?

Yes, there is plenty of memory in the Pro Mini for that. The signal generator will output whatever frequency you program it too with your code and depending on how you write your code, it will do that at powerup.

Excellent. I will have to amplify the output this frequency generator, is there a recommended amplifier?

Hi Amin.

Not that I’m aware of.

As long as your output is between 20 and 20kHz, a regular audio amp would work. Above that, you’d need an amplifier or op-amp that’s designed for the frequency range you’re outputting.
