Could anyone tell me what is this?
(Found in MagPi magazine #134, page 89.)
If you adjust the levels, you can see better:
It looks like a stackable USB 2.0 hub, to sit under the Argon ONE. USB-B socket for input on the back, two downstream USB-A sockets on the back, and probably two on the front. Maybe USB-C for power input on the back? All purely speculation…
No sign of it on the Argon product website though?
Probably it is the same as in another thread:
It seems to have a button on the front right, and probably LEDs (?) on the front left.
