Do you have some basic LEDs to connect BlinkStick Pro to test if the chip is not damaged?

This tutorial shows an RGB LED, but you can connect the same way some simple single color LEDs too:

> You can connect a basic RGB led to [BlinkStick Pro](https://www.blinkstick.com/products/blinkstick-pro). The schematics above is for common anode LED. Set [BlinkStick Pro mode](https://www.blinkstick.com/help/tutorials/blinkstick-pro-modes) to 0. You can use the schematics below for common cathode LED. Set [BlinkStick Pro mode](https://www.blinkstick.com/help/tutorials/blinkstick-pro-modes) to 1 for this setup. Use 330 Ohm current limiting resistors.
