Wanting to switch to the Trinket below:

As I just don't need the bluetooth or other capabilities of the feather, and the trinket is much cheaper.

Anyone know if they are compatible, and if i would just wire in in the same way, or if i should be using another microphone?

Also assuming you would upload to them and program them up in the same way?

Really appreciate any help, thank you all!

  • The two boards are obviously different and use different processors - so you may need to use a different pin for the analogue input.

    You haven't said what you actually do with the microphone signal  - so it's not possible to tell from here if the the processor differences matter.

    I hope you won't mind me asking this - and that everyone at E14 is happy to have you on board - but would no one at RS or Design Spark help ?

    If you could use the Trinket (not pro) you can get it from Amazon for even less (£6.79).
