Versions of Crazyradio dongles. Is there a difference between Crazyradio and Crazyradio PA?

Question

Arduino

There are very similar Crazyradio offers on Ebay ( https://www.ebay.com/itm/Crazyradio-2-4Ghz-nRF24LU... )
and AliExpress ( https://aliexpress.ru/item/-/4000529687227 ) .html?sp... )
It looks very similar, but I take into account the significant difference in price, if you look closely, then outwardly there is a difference in the elements of the board. In the description, the nRF24LU1 + chip is indicated everywhere. There are no different versions on the site. If anyone bought or used, tell me please.

Answer 1

The PA version has a LNA low noise amplifier that raises the output power to 20dbm.
on the board this is element D4
