Revision as of 17:08, 4 April 2021
- Two independent RGB LEDs behind the logo on the back of the lid
- Two RGB LEDs on near the power button
- One RGB LED underneath the power button
- Several white LEDs used to backlight the keyboard (These can be controlled in groups, see video for demo)
Hardware:
- IS31FL3199 - 9 Channel LED Driver with I2C interface
- Rohm SMLP34RGB2W - 4-pin RGB PICOLED(R) for "LED-L", "LED-PWR" and LED-R
- CDBQR0130L-HF Shottky Diodes - 3 x used to make the red leds of the 3 x RGBs also display the "FAULT 1 / 2" and "CHG-STAT" outputs.
- PCAL6524HEAZ GPIO expander
