Assemble Circuit

Use your soldering iron to heat up the connections on the back of your NeoPixel matrix, and remove all but one power, one ground, and the data in wire. Reposition the wires to face towards the center of the matrix instead of outwards.

If using FLORA and the FLORA BLE module, solder the collowing connections:

  • matrix DIN -> FLORA D6
  • matrix 5V -> FLORA VBATT
  • matrix GND -> FLORA GND
  • BLE 3.3V -> FLORA 3.3V
  • BLE TX -> FLORA RX
  • BLE RX -> FLORA TX
  • BLE GND -> FLORA GND

Plug your battery into the JST port and a USB cable to the micro USB port. The USB port on your computer may not be able to supply adequate current to the matrix, so be sure your FLORA's power switch is also set to ON to be sure the battery is supplying power.

If you're using the Feather 32u4 Bluefruit LE, it's even easier with only three connections:

  • matrix DIN -> Feather 6
  • matrix 5V -> Feather BAT
  • matrix GND -> Feather GND
