Adafruit CharliePlex LED Matrix Bonnet - 8x16 Cool White LEDs
128-LED 16x8 CharliePlex LED matrix Bonnet in cool white, for any Raspberry Pi with a 2x20 connector. Driven by a built-in I2C CharliePlex controller.
Pinout
- 5V
Raspberry Pi 5V supply used to power the LED matrix on the Bonnet.
Type · powerVoltage · 5V supply, per Adafruit Learn: LEDs are powered from the 5V supply. - GND
Raspberry Pi ground connection for the Bonnet.
Type · groundVoltage · 0V ground reference. - SDA
Raspberry Pi I2C data line used by the IS31FL3731 LED-matrix driver.
Type · i2cVoltage · 3.3V logic, per Adafruit Learn: SDA/SCL logic level is still only 3.3V. - SCL
Raspberry Pi I2C clock line used by the IS31FL3731 LED-matrix driver.
Type · i2cVoltage · 3.3V logic, per Adafruit Learn: SDA/SCL logic level is still only 3.3V. - Address jumper
I2C address-select jumper for the IS31FL3731 driver; public connector/control content, not a Raspberry Pi header pin.
