Using NRF24LE1 to play a previously recorded sound.

[DiegoVP]

I'm using this module to develop a toy that needs a couple of sound effects. I just don't want generated tones but previously recorded audio files no longer than one second each. Please provide me with some advice. I'm open to any config, the only must-have is the NRF24LE1 module. How can I achieve this?

Hi 

It's technically possible to play some sounds using the PWM module of the nRF24LE1 device, but it is hardly an optimal solution. 

What audio quality do you need, and how many seconds of audio in total do you need?

The nRF24LE1 only has 16kB of internal flash, so if you plan to store the sounds internally you don't have a lot of available room. I assume you will use some of that flash for the firmware also?

Best regards
