15x7 CharliePlex LED Matrix FeatherWing - Warm White
105-LED 15x7 CharliePlex LED matrix FeatherWing in warm white. Driven by an I2C CharliePlex driver; compatible with all Feather boards.
Pinout
- 3Vsecond from left
FeatherWing power and logic supply. Adafruit Learn states the LED matrix uses only the 3V pin for power and logic.
Type · powerVoltage · 3.3V Feather rail; Adafruit notes typical current draw around 40mA depending on lit LEDs. - GNDfourth from left
Ground return for the FeatherWing LED matrix. Adafruit Learn states the board uses GND for power and logic.
