The LED Strip Bricklet is now available in version 1.1. The new version of the LED Strip Bricklet has protective circuitry to protect WS28XX pixels from voltage spikes. The firmware/API of the Bricklet does not need any changes, software for the old version will be 100% compatible.
The Bricklet was sold out for the last ~2 weeks. Open backorders from this period were shipped today. We are sorry about the long delivery time for the LED Strip Bricklet, we did underestimate the “Christmas-demand” for LED things :-).
