Required Arduino Pro Micro specs?

Open ELLIOTTCABLE opened this issue 6 years ago • 1 comments

I'm a bit of an electronics noob; but the BOM only lists "Arduino Pro Micro", with no link or anything …

Amazon lists a ton of clones for that search — is the implication that any one of them will work? (In particular, there's at least two for sale, directly from SparkFun, with substantially different specs: a 5V version @ 16MHz, and a 3v3 version @ 8MHz.

Plz help a noob! <3

@ELLIOTTCABLE you'll want the 5V (16Mhz) pro micro.

You can make it work with a 3.3V (8Mhz), but that requires a small change to the receiver firmware as well as the QMK code. (I got a 3.3v clone by mistake.)
