The "Pluto Plus" (aka Pluto+) is an unofficial and upgraded version of the Analog Devices ADALM Pluto SDR. It is currently available on Aliexpress and Banggood stores. In his latest video Tech Minds reviews a Pluto+ SDR that he has received, noting that it has all of the features that should have been in the original Adalm PlutoSDR.

He notes that the PlutoSDR+ has various improvements over the PlutoSDR such as that it comes in a metal enclosure, has four SMA connections (2x TX, 2x TX), a Gigabit Ethernet connection, a microSD slot, external clock input, 0.5PPM TCXO, fine tunable clock via resistor, a PTT key port and a DFU key.

In the video he goes on to show how to set up the PlutoSDR+ before testing it out on a QO-100 satellite setup, noting that it works perfectly and without any signal drift noticed.
