Signs pointing to this chip

• Cracked joints after a bend.

Helpful to know

The 3rd gen iPad Pro 11 shares the 343S00480/343S00544 auxiliary power IC with the iPad Air 5, but this 182-pin part is listed for the iPad Pro 11 only. Measure each chip's rails before choosing which to replace.

Fit with a preheater and fresh flux, then test boot, Face ID, cameras and charging before closing the iPad. On cellular models, check that mobile data connects as well.
