As some of you may have noticed, the current LED-ring deck doesn’t play nice with the Crazyflie 2.1 Brushless. The culprit? A resource clash between the DSHOT motor signals and the WS2812 LED driver used for the LED-ring.
But good news! We’re prototyping a new LED deck that solves the conflict by switching to I2C communication. Not only does this fix the compatibility issue, it also gives us a chance to improve its features. Here’s what we’ve improved so far:
- Using a highly efficient high powered LED
- DC/DC driving circuitry to improve LED driving efficiency
- 1W on each channel (red, green, blue, white)
- LEDs on both sides so it can be mounted both on top or on bottom of the Crazyflie
The LED we’re using is very powerful and the light is emitted from a small area, so a light diffuser is needed to get a more pleasant light. Designing something that can be manufactured is the next step of the project. Make sure to follow our blog to get more updates on this project.
