Matrix Power Cable

The 64x32 RGB matrix display features a power cable. The wiring has been shortened and simplified to make the wiring more manageable during assembly. 

Feather & FeatherWing Setup

The Feather M4 Express has a 12-pin and 16-pin strip of male header pins soldered to the bottom of the PCB. The RGB Matrix FeatherWing has 12-pin and 16-pin female headers soldered to the top of the PCB. The 2x10 female socket soldered is to the bottom of the FeatherWing.

JST Cables

Four JST cables are used to connect the various components to the Feather and FeatherWing. Here's a list of the cables and where they're connected to.

  • 2-wire male JST: Arcade Button
  • 3-wire male JST: STEMMA Speaker
  • 3-wire male JST: IR transmitter
  • 2-wire male JST: IR receiver

Feather & FeatherWing Connections

Double check the wires and cables are ready for soldering to the PCBs.

Solder Cable – IR breakbeam receiver

Begin by soldering the 2-wire JST cable to the ground and 3V pins on the Feather. This cable will connect to the IR receiver. The wiring is soldered to the bottom of the Feather.

Solder Cable – IR breakbeam TX

Solder the 3-wire JST cable to available ground and 3V pins on the Feather. This cable will connect to the IR transmitter. The white wire will be connected to the A1 pin on the RGB Matrix FeatherWing.

FeatherWing Connections

The remaining JST cables will be soldered to the RGB Matrix FeatherWing.

Button Wiring

Soldered the second 2-wire JST cable to the ground and D4 pins on the bottom of the FeatherWing. Reference the pins on the Feather to ensure the pins are correct.

Solder Signal – IR transmitter

Solder the white wire from the 3-wire JST cable to the A1 pin on the bottom of the FeatherWing. This cable will be used to connect the IR transmitter.

Wiring STEMMA Speaker

Solder the wires from the second 3-wire JST cable to the following pins on the FeatherWing. White wire to A0, black wire to ground and red wire to 3V.

Wired Feather & FeatherWing

The wiring is complete and ready for plugging in the various components.

Wire Check

Double check the wiring is correct.
