A TCA9548A clone module has the same pin order as the Adafruit board but rows 17.78 mm apart instead of 15.24 mm. Issue #905 said the clone was one pitch narrower. The photo and caliper said one pitch wider, and "the footprint follows the measurement." The fix doubles the header pads with the same pad numbers so the netlist doesn't change.
