Tripler exposes duplicated Feather I/O pins; Adafruit says the tripler pinout is the same as the doubler with one extra footprint, and the doubler ties the Feather I/O pin sets together so each I/O pin is accessible.
Connected power rail for Feather 3.3V prototyping holes.
Connected ground rail for Feather prototyping holes.
One Feather/FeatherWing footprint connected to the shared duplicated I/O pins.
Second Feather/FeatherWing footprint connected to the same shared pinout as the doubler/tripler.
Shield
Verify supply voltage and logic levels before powering up.
Module pins: 3.3V rail, GND rail. Schematik maps them to your board in the app.
About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.
