It's a bit more complicated - which I admittedly missed on the dealer's site I checked yesterday, sorry.
Check out the paragraph at top of the page. https://mikrotik.com/product/crs112_8p_4s_in
The switch It comes with a 24V PSU that powers the device and the MT-style passive-PoE, and you can do total of 2.8A of the 24V at all ports with max 1A per port. That's quite a plenty.
Then you can buy an additional 48V PSU (either 70W or 96W) for 802.3af/at PoE/PoE+ to power stuff like cameras and IP phones and plug it into a dedicated socket in parallel with the 24V.
The docs for hAP lite don't say anything about MT passive PoE input, only USB 5v input.
That's why I didn't recommend that one for purchase (didn't know you have it already).
Something you can use is a "PoE splitter", the reverse of injector. Takes a data+PoE signal from a switch and offers two cables, one ethernet and one power.
There are some variants ones meant for devices like Raspberry PI with already offer 5V output on a micro USB plug out of the box.
Others would have a barrel plug (typically 5/12V selectable) and would need another adapter.
Just pay attention to the specs - some can drain MT-style passive PoE, some do 802.3af standard (48V with smart negotiation).
I have 'bout a hundred of various types deployed to be able to use the PoE on/off option in managed switch for remote reset of flaky embedded hardware, and I'd lie to you if I'd say 100% of these splitters are 100% compatible with every switch and device
