A1 supports one AMS lite for up to four colors. AMS, AMS 2 Pro and AMS HT use the A1-series AMS HUB SA013 with firmware 01.07.00.00 or later. That route supports up to four units, without mixing AMS lite; cable generation and drying conditions still apply.
Creality’s U.S. product information lists CFS and the K2 Plus PEI frosted build plate; its general replacement guide identifies the K2 Plus integrated nozzle. Hardware fit is not universal material support: TPU must not pass through CFS, and nozzle choice depends on the filament.
US specifications list 0.2/0.4/0.6/0.8 mm nozzles for K2 Plus, a 350 °C maximum and an included 0.4 mm nozzle. Separately, Creality’s general CF guidance advises against 0.2 mm and prefers 0.6 mm, followed by 0.4 mm, with the documented temperature and cleaning conditions.
Creality’s U.S. K2 Plus options list up to 4 CFS units and 16-color printing; 1 CFS provides 4 slots. Separately, the general filament guide says not to feed TPU through CFS because it can bend and cause loading or unloading failure.
Insta360 X2 has Type-C USB 2.0; that connector specification does not establish every accessory pairing. X2 supports the Insta360 Mic Adapter (Vertical Version), not the X3 Mic Adapter. It also supports the X2 Fast Charge Hub and X2 Lens Cap; those exact names matter when replacing older kit.
Insta360 X3 has Type-C USB 2.0; that connector specification does not establish every accessory pairing. X3 supports the X3 Quick Reader and X3 Fast Charge Hub. The X4 Quick Reader and X4 Fast Charge Hub are not supported, even though some simpler X-series accessories are shared.
