Probably just the same PCBA is used in both products.
Just compared the specs of those devices. Could indeed be the case.
But something is wrong there with those specs. Map Lite is listed as not having USB powering option which it certainly has. I have 2 in front of me and that's more or less the only way I power those !
And I never noticed cAP Lite should have it according to specs (why would it ??).
Anyhow, I know that mAP Lite can also be powered using 802.3af/at (at least the ones I have).
And passive PoE as well.
