No, the GoPro Hero12 Black is not compatible with the Rode Wireless GO II.
Rode Wireless GO II's wired outputs are 3.5mm analog and USB-C digital. GoPro Hero12 Black has no native 3.5mm or wired mic port -- GoPro's own tech specs list no 3.5mm jack, only Bluetooth Audio Support (not Wireless GO II's RF transmission system), and route wired mic input through the separate Media Mod accessory (explicitly listed as H12B-compatible). Requires GoPro's Media Mod.
