From 0fa2786b0c90583bda477ab724aa5be1e65d77fe Mon Sep 17 00:00:00 2001 From: Richard Date: Thu, 3 Sep 2026 10:54:29 -0700 Subject: [PATCH 1/2] docs(bom): warn against the similar but incompatible Adafruit 2472 BNO055 board The BOM's IMU link goes to the correct Adafruit 4646 breakout, but Adafruit also sells the older non-STEMMA-QT BNO055 breakout (product 2472). It looks nearly identical and its data pins are in a different order, so it does not work on the PiFinder hat. A couple of builders have been caught out, so add a note to the line item.
