- pwm
- brightness control notes
- Extra 5-bit brightness control by overlaying 400Hz PWM on LEDs
- channel current
- 22mA
- channel current notes
- 19-22mA in 5050 package, 10mA for 2020 package; extra 5 bits control PWM, not current

- gpio max
- 5V
- gpio min
- 3.5V

- 5V
- led voltage notes
- Datasheet claims "26V Vds, Max" but LEDs are built-in and share power with 5V VDD
- max pixels notes
- Clock pulse gets shorter by a few ns every pixel. After ~250 pixels, the clock signal can no longer be reliably retrieved.
- max pixels per string
- 250
