CNX Software takes a look at the passively-cooled Raspberry Pi-sized Ryzen Embedded dev board.
"That’s quite a big package for a board supposed to be Raspberry Pi-sized… But there’s a reason, as the board comes with plenty of accessories including a massive heatsink, a beefy 12V/5A power supply and accompanying power cord, some cables and screws, a utility/demo DVD, a quick reference guide, and a battery warning. The heatsink includes four through holes for mounting, as well as orange (CPU) and black (RAM) thermal pads for cooling."
